2015.40 Junction File -- Where? What size? for a Nuvi 2689?

 

I never had a junction file for the 660, so I didn't follow those threads much, other than to take note that upgrades would sometimes not load one, or load a smaller file.....

Now that we own a Nuvi 2689 I guess it's time to take notice.... and start asking questions....

On the 2689, where would the junction file reside.....

And What size or sizes would it be for 2015.40?

I'm trying to determine if there are 2 different size files for this unit.... or not...

I do believe I saw the Junction File in operation in 2015.30, and it occupied half the screen....

Is the difference between the small and large Junction File if it displays on half the screen or whole screen?

I realize I'm coming to this part of the 'Party' late, and I thank you for your comments....

ok...I don't have that model but the .JCV file is most likely located in the following path in your model
x:\.system\JCV\DxxxxxxA.JCV

The ".system" folder is a hidden folder and you may need to change some PC settings to view it along with placing your GPS into "mass storage mode" before you can view it's contents.

Your GPS uses split screen photo real pictures and the size for 2015.40 for all practical purposes will be very close to what you already have for your current map, perhaps a "little" larger.

There may be 2 sizes for NA 2015.40 if it's handled by Garmin like most other Nuvis. The large file having coverage for all of North America and the smaller for US & CAN only.

What determines the file sizes are very model dependent and there are quite a few variants.
1. full screen or split screen
2. screen resolution
3. number of photos and the photo resolution
4. the video rendering technology used in your model

For older models which have very limited memory (7x5, 8x5, 1xxx series) the also provide a "Lite" version with much less coverage and or picture quality (but much smaller file.

When you do your lifetimee map update your new map will have the same coverage that was provided when you purchased the GPS. The map update process will automatically install the proper .JCV file for the map coverage you have. In fact, they are a matched set of files.

JCV file on newer nuvis

The junction file is likely in your nuvi's .system\JCV folder. It'll be the only file in the folder except for a possible tiny .sum checksum file.

Since it's a split-screen JCV file, it's likely to be just under 500MB.

The "large jcv" file really doesn't apply to split-screen nuvis (and currently is not available from Garmin to manually download for the current 2015.40 map) but is around 800MB. More on why it doesn't apply (scroll down to Junction View):

http://www.poi-factory.com/node/37552

Your ~500MB file is correct for your nuvi. When reading about the "large" and "small" JCV files, the discussion is primarily designed for owners of the old nuvi 8x5, 1390 and 14xx devices where the "small" file is under 26MB and the "large" is under 900MB.

[Edit] Good post, frank508. Note, though, that the nuvi 7x5 series (along with some zumo models, I think) does receive the "large" jcv file.

Thanks for that info.... I

Thanks for that info....
I find, in the

The 2689

The 2689 is a model that displays junction views in "split screen" so the JCV file for the full North America 2015.40 map update should be approximately 490414KB.

Great info

I'm about to jump onto the bandwagon with the 3597LMTHD and as JanJ have not followed this particular subject since my 255WT doesn't have these features.

Jgermann explanations / definitons are VERY helpful but if ever he could add coordinates for simulation purposes the user would beable to visually see the differences between a junction view / a PhotoReal junction view & a Bird's Eye junction view. Just a friendly suggestion that would be beneficial for many of us.

Keep up the good work everyone, the wealth of information on this site is simply amazing smile

I had to wait quite a long time to see all the types of JVs on my 3597. In addition to PhotoReal standard JVs, there are Birdseye JVs and Active Lane Guidance. I saw standard and birdseye near home but had to travel to Greater Denver to see my first ActiveLaneGuidance. And for what it's worth, I still haven't been to a place (Las Vegas?) where I'll be able to see 3D buildings.

PS—with the 3597 and other devices that offer a 3D Digital Elevation Map (DEM), you should see a shaded relief overlay on the standard City Navigator map. Driving along the South Rim of the Grand Canyon along Hwy 64 may be the best example.

Las Vegas does have 3D Buildings.

@canuk, added info to FAQs and used CraigW's links

Thanks CraigW + Jgermann

The manner in which you've both immediately answered my questioning and then adding a FAQ, clearly shows without a doubt how POI Factory is in a class by itself in regards to other GPS forums.

JCV

JanJ on one of the link that t923347 provvide he wrote that JCV for the 2015.40 should be when be released D3191170A.jcv,I believe that the D3191160A.jcv is for the 2015.30 and not for the 2015.40..

JCV It would then appear

Looking at you profile and GPS devices, why do you want the file?

Nuv i 2598LMTHD 2014.40 GE update, No JCV file?

It took about 39 minutes to update PC and GPS (Optimum, Ultra-50 speeds), but I cannot find any JCV files in this update.
GE Software Version 4.80 (updated w/previous version).
Full coverage of North America 2015.40.
Some posts mention JCV file in device system folder but system folder does not show up in file explorer (display hidden files option on).
Any ideas?

You need more than just having hidden files visible in your Folder Options. See (especially PC tips 4-7):

http://www.poi-factory.com/node/30393

Then you also need to make a change to nuvi 2598 (which wasn't needed on your older nuvi 765). See:

http://www.poi-factory.com/garmin/problemsolver#system-folde...

Once done, you should see your nuvi's .system folder and its subfolders and files.

It would be nice if Garmin

It would be nice if Garmin gave us complete control of "which" files we can download and where we want to put them.

It is a PITA to have lifetime maps and have to "find" the full/complete junction view, as Garmin doesn't think you have enough space on your SD card (that has 5 GB free).

The beauty of MTP mode is that it's more idiot-proof—or for us cool folks cool , prevents an inadvertent slipup since most of the files are not accessible or even visible.

Having said that, I leave my MTP nuvis in MS mode permanently since I backup my nuvi after every map and software update and I don't want to switch modes all the time.

MAPS

After installing 2015.40 (& re-installing)using Garmin express 4.0.13.0, I end up with only one map in my 2598lmthd:
gmapprom.img 2,390,784 KB
myMaps: CN North America NT, 2015.40 ALL

Not supported.

I don't believe your 2598 supports 3D terrain view (gmapdem) or 3D buildings (gmap3D).

Because the large view is easier to see when it's displayed. Just a personal preference on my part.

I have to agree ... there is no good reason for Garmin to not download the full coverage JCV file if there is room for it (on internal storage, SD card or clone). I am sure they could add this capability to Garmin Express with very little additional programming.

It is even more sad that Garmin has not published the full screen full coverage 2015.40 JCV file for separate download. This forces legitimate loyal customers to go to nefarious sites to find and get the file.

Many of us in this forum have scolded members when they go to sites that offer pirated content ... so what does Garmin expect them to do?

But the question I have is if Garmin hasn't released the 2015.40 large .jcv, where did this file on other sites come from?

It

It came from a person that got the full screen large JCV file as part of thier regular map update. For example, owners of a Nuvi 755 report they received the full large file. Once they obtained the file they posted it to the download site.

Prefer Split View

For those of you wanting to get the full screen version of junction view, please read.

I just tried out the full screen version on my 3490lmt and didn't like it. You get a full screen shot of the junction when you're a little less than one mile from the exit. After a couple of seconds, this image disappears and you go back to the full navigation map until you complete the exit.

I prefer the split view because the split view junction image remains on the screen all the way until you actually exit. I prefer this behavior, and I don't think you really get that much more information from the full screen junction view.

My 2 cents...

--
3490lmt

+1 but

I agree with your comments IF you own a Nuvi that supports split screen junction views but I suspect that almost everyone that wants the Large Full Screen Junction View file own Nuvi models that only support full screen views and are getting a very small, limited number of views, JCV files with their map updates, even when some of these devices have plenty of room in internal storage to hold the bigger file.

nuvi 1450lm

.JCV files are confusing I have a nuvi 1450lm and I up dated to CA north America 2015.40 with it came the .JCV d3153170A the lite one. I guess my question is the D2335200A.JCV is that the correct file for the full JCV with lane assist for my model ?

alandb's finding for the large JCV file for your nuvi 1450

Your nuvi 1450 should use the same large jcv file as the nuvi 7x5 and 8x5 series devices and alandb has stated in another thread:

I have completed the 2015.40 map update on a clone of my 755T, and Garmin Express did again provide the Full Screen Full Coverage JCV file. It is as follows:
03/24/2015 11:22 AM 855,090,875 D3060170A.jcv

The above is correct for folks installing the entire North America map update. It may be that if you installed less than all of North America that a different "large JCV file" is correct. If someone can confirm this, it'd be appreciated. From the GPS Underground site, it appears that for devices with full screen Junction View with the 2015.40 map which is USA/Canada only (not all of North America) that the correct JCV file is:

D1279250A.JCV - US & CA only Fullscreen (although I haven't confirmed this—it appears that GPS Underground also offers unlocked 2015.40 maps which seems to be hacked/pirated maps so I refuse to download anything from the site.)

Don't worry about Lane Assist. Unlike Junction View, Lane Assist is built into the map file and is not a separate file like the JCV is.

I agree

I agree, and that is why I have not mentioned the actual name of the download site here. As far as I'm concerned the Large Full Screen Junction View file should be made available to all those who need/what it but it should come from Garmin and not from some site that deals in priated maps.

My opinion

I find the split screen junction file to be useless. The map is too small and provides no useful information. The photo screen is too small to read. I don't want to be limited to it.

True, but...

There is merit in what you say. The one "feature" of the full screen JV, however, is its presence for such a short time and rapid disappearance without human finger-tapping intervention to bring it back and that is my reason for preferring the split-screen view.

I've disabled junction view altogether

I've disabled the junction view altogether by renaming the extension of the JCV file.

I've found that the split screen junction view runs into problems when you have more than 2 highway signs. It is only able to display the 2 rightmost highway signs. If you need to take a split or exit to the left of these 2 rightmost signs, the arrows will still be drawn underneath the 2 visible signs misleading you to take one of those exits.

After seeing this, I switched to full screen junction view at the same highway spot. The full screen was accurate, and the arrows were drawn correctly under the 3rd sign located to the left of the other 2 signs on the right side of the highway.

BUT there's a problem with full screen as well. The junction view images aren't updated very frequently. There was some highway work completed about 2 years ago in my area. According to the full screen junction I should be going right when in fact the correct way was to go left.

Funny thing is, if you listen to the verbal directions (and look at lane assist) they correctly told you to go left. This means that the verbal direction and lane assist info WAS updated but not the junction view image files.

I've determined that the best way to navigate is by listening to the verbal instructions. I only look at my gps to see where junctions are coming up (tip of white arrows on highlighted route) and if there's a hairpin turn coming up.

Now I'm wondering if the "active lane guidance" has similar inaccuracies as mentioned above.

JCV files

I came to this thread looking for a download link. Does anyone know if Garmin decided to stop making the files available? If not can anyone offer a hint as to where to find the file.

Thqanks

Garmin.

Garmin has remained conspicuously silent about not publishing the 2015.40 JCV file. We can only assume they made a conscious decision to withhold it.

You can find the file through Google at some download sites that specialize in pirated content. Beware and access these sites at your own risk. Your best choice is to get the file from someone with a 7x5, 1390, 14x0 nuvi or 660/665 zumo.

Hmm, I wasn't aware that the 1390 and 14x0 series got the large JCV file. If that's correct, jgermann may want to change his Glossary entry for Junction View:

http://www.poi-factory.com/node/37552

as it states the 7x5 is the only nuvi to receive the large JCV file.

From the Glossary:

CraigW and alandb have stated

1) All models that receive the split-screen Junction Views are given the correct JCV file during map updates. (The one "exception" to this is the small group of split-screen device owners who prefer and are willing to manually download, install and then view the large full-screen JCV file and its views.)

2) Of the older devices that show full-screen JVs, it is the nuvi 1390, 14xx and 8x5 devices that receive the tiny JCV file from Garmin during map updates--and these are the devices that will benefit most from manually downloading/replacing the large JCV to their device.

3) Of the older devices that show full-screen JVs, it is only the 7x5 series that receives that large JCV from Garmin during map updates, and therefore they do not need to manually download or use the "large" JCV file.

Help please

Region Updated Also Determines Which JCV File

.JCV files are confusing I have a nuvi 1450lm and I up dated to CA north America 2015.40 with it came the .JCV d3153170A the lite one. I guess my question is the D2335200A.JCV is that the correct file for the full JCV with lane assist for my model ?

I only get the large JCV files for my 755t (and for the record, any uploaded version elsewhere came from someone else). For the 2015_40 map update, I see the following 4 JCV files were available:

Region 1 (Full Coverage of North America)
Region 11 (Southern US & Mexico)
D3060170A.JCV

Region 2 (US & Canada)
Region 9 (East)
Region 10 (West)
D1279250A.JCV

Region 3 (Canada + Border States)
D2334200A.JCV

Region 4 (Lower 49 States)
Region 5 (Lower 49 States NE)
Region 6 (Lower 49 States NW)
Region 7 (Lower 49 States SE)
Region 8 (Lower 49 States SW)
D2335200A.JCV

My error

Garmin has remained conspicuously silent about not publishing the 2015.40 JCV file. We can only assume they made a conscious decision to withhold it.

You can find the file through Google at some download sites that specialize in pirated content. Beware and access these sites at your own risk. Your best choice is to get the file from someone with a 7x5, 1390, 14x0 nuvi or 660/665 zumo.

Hmm, I wasn't aware that the 1390 and 14x0 series got the large JCV file. If that's correct, jgermann may want to change his Glossary entry for Junction View:

http://www.poi-factory.com/node/37552

as it states the 7x5 is the only nuvi to receive the large JCV file.

My error ... you are correct CraigW. I incorrectly listed devices that NEED the full screen full coverage JCV file, not the ones that received it. As stated earlier, the 7x5 series is the only NUVI that got the full coverage file with the 2015.40 map update. User danham over on the gpspassion forum confirmed that the Zumo 660 also received the full coverage file with the map update, so I assume the zumo 665 did as well.

So ... my earlier post SHOULD have read: "Your best choice is to get the file from someone with a 7x5 nuvi or 660/665 zumo." My apologies to the POI Factory members for the misinformation.

From the Glossary:

CraigW and alandb have stated

1) All models that receive the split-screen Junction Views are given the correct JCV file during map updates. (The one "exception" to this is the small group of split-screen device owners who prefer and are willing to manually download, install and then view the large full-screen JCV file and its views.)

2) Of the older devices that show full-screen JVs, it is the nuvi 1390, 14xx and 8x5 devices that receive the tiny JCV file from Garmin during map updates--and these are the devices that will benefit most from manually downloading/replacing the large JCV to their device.

3) Of the older devices that show full-screen JVs, it is only the 7x5 series that receives that large JCV from Garmin during map updates, and therefore they do not need to manually download or use the "large" JCV file.

As CraigW suggests, the glossary may need to be changed. Can someone with these devices give us some guidance?

I have 1390T and every time I do an update Garmin gives me the small jcv file. I have to download the full jcv and install it on a SD card. I haven't upgraded it to 2015.40 but I'll bet they will give me the small jcv.

NUVU 765T/ 2598LMTHD Map 2015.40 file sizes

After updating my 765T & 2598LMTHD GPS units with the 2015.40 update, both units end up with the same map size: 03/25/2015 09:57 AM 2,390,784 gmapprom.img

Another post specifies a different size:
03/24/2015 09:57 AM 2,448,162,816 gmapprom.img

Are my updates missing something?

CN North America NT, 2015.40 ALL

All is well

All is well. 2,390,784KB is 2,448,162,816bytes.

A KB is 1024 bytes.

DIR command

I used a command prompt window with the command "DIR > dir.txt" to capture my file sizes and copy them to my post in the 2015.40 map update thread. That method shows the file sizes in bytes.

When you look at file sizes in a Windows Explorer window, you normally see the sizes in kilobytes. You can right click on any file and select Properties to see the file size in bytes.

My bad, I should have known better and did a Windows Explorer properties check. Thanks.
