Large JCV file for CN NA 2013.40

 

I posted this in the map update thread, but thought it might deserve it's own thread:

A user over on the Garmin Software forums is reporting that Garmin is again posting the Large JCV file on their site. Here is the post: https://forums.garmin.com/showthread.php?34677-CN-NA-NT-2013... and here is the download link: http://download.garmin.com/support/2013_40/NA/JV/D3060090A.J...

I criticized Garmin and posted a "shame on Garmin" comment during the last map update because they failed to make the large JCV file available to their loyal customers. If they have reversed this decision, my hat's off to them for once again doing the right thing.

Note: just downloaded this as a test and compared it to the file I got with my 755T map update. Same file! Thanks Garmin!

Kudos!

Many a kudo is due to Garmin. I hope this continues in future quarterly map updates.

Thank You Alan

Just what I needed. I will update my maps later tonight.

Amazing. What great news. I'm downloading now--even before doing a single map update.

You were the first person I thought of, CraigW, when I found this. Glad you were able to start the download before Garmin changes their mind again.

This is quite a good thing.

This is quite a good thing. I wasn't sure if they were going to do this, which is why I posted my alternate links in the other thread.

Discrepancy with size

The Garmin Web site says the large JCV size is 756.24 MB; but I just downloaded it and mine is slightly smaller at 733.15 MB. Anyone else get the same result?

My results. It depends a bit on where you look on your computer to see the size of the files, although I agree with spokey that 733.15 isn't one of them.

Last map's (2013.30) results, the ..80A.jcv file:

774,550KB; or, by checking the file's properties:
756MB; and Size: 793,138,402bytes; Size on Disk: 793,141,258bytes

This map's (2013.40) results, the ..90A,JCV file:

774,395KB; or by properties: 756MB; and Size: 792,980,375bytes; Size on Disk: 792,981,504bytes.

The new jcv file for the current map is therefore smaller than the previous one by a slight amount.

Re-ran the download

I wasn't comfortable with the first download so I downloaded the file again just now. The file size this time is 774.395 MB so I feel a lot better about that. Time to do the map update.

I've watched this JCV debate every time we have an update. I've not bin too concerned, until this update. I d/l the large JCV file and wondered why it was 30% larger than the ones on my units. Strange enough that they are both the same size on both units and a bit smaller than the last update. My 3590 with photoReal and Bird's Eye view should have a larger jcv file I would think. Gonna install through lifetime updater and see what happens. Hopefully I don't end up like Juggernaut did with his 775. laugh out loud

There's two parts to the jcv file size debate:

-screen image size: full vs. half screen jcv

and

-number of jcv locations included: Garmin created a truncated version of the jcv file by eliminating many of the intersections that would pop-up a jcv. They did this due to units with insufficient capacity for the full number of locations (eg, Nuvi 1490).

At first I wanted the full screen image, and of course, all the locations for which jcv's exist. I have grown to prefer the half screen image (so I can see the route/directions simultaneously). In either case, I want all locations for which jcv's exist to be displayed. BTW, touching the split screen jcv will close the jcv image and restore the full screen view, if you don't want to wait for it to disappear from the screen on its own.

I just wish they could figure out a way to display the map with the split screen JVC, and still leave the SPEED displayed on the screen. As soon as the split view appears it covers up the speed display which doesn't reappear until you've completed the maneuver being shown in the view.

I've grown to rely on the Nuvi's speed readout because, like all Volkswagen models, the vehicle speedo is out so much.

If i'm reading you right, to get all locations, I would need the large jcv but then I would no longer get the split screen view which is what I also want?

Hmm.. now that's just plain weird. Now my JVC file is 11 megs smaller using Lifetime map updater, and still 30% smaller than the large one

Every time there's an update the maps will always get bigger. I transfer my maps with maps mapsource. I wish they would update it. But we can't have it all.

JCV Files

@Speed2: The largest half-screen JCV file should contain all the same junctions found in the full-screen file. As a result it should be approximately half the size of the full-screen file. If your file is only 30% smaller than the full-screen file, wouldn't the bird's eye views account for the size difference? After all, that's a feature reserved exclusively for the 3000 series nüvis and won't be found in anything less.

That's an iffy question. There is quite a difference between the junction view of the 3590 and 3790, but both file sizes are identical.

Then unless the individual

Then unless the individual bird's eye views within the file take up additional space, for whatever reason, the bird's eye JCV should have the same number of junctions in it as the "standard" version. In fact, is there anything preventing you from taking the 3590's JCV file and dropping it onto the 3790? If you did this, would you get bird's eye junction views on the 3790?

Another iffy question, never tried. Never thought of it either. Didn't think of comparing JCV files before today. The 3590 has a larger screen...so, just maybe the 3790 is too small to show it. It's the only thing that would make sense since they are both identical files.

What Is A JCV File

junction view file

for lane guidance. The large JCV file referenced in this thread applies primarily to the 7x5 and 8x5 series nuvi (and maybe 14xx?).

The Garmin 1350 does not support junction views. A junction view shows a photo of an upcoming interchange or junction.

Update

As a matter of fact, the 3590 has seen 4 map upgrades,
I compared those JCV files with the 3790 and they are all the same size and file name. No where does it say that the 3790 has photoReal and Bird's Eye view. The file should be larger. gonna load the large one onto the 3590.

Ugh, this means your views will not be photorealistic and most likely, you're missing many many junction views. I can confirm your results since that's what my 855 received with this map update as well.

The large 750MB-ish jcv file can be downloaded directly from Garmin to your computer and works great on nuvi 855s. Then get a SD card to fit in your 855, create a \garmin\jcv folder on the SD card and copy the large D3060090A.JCV file there. Now either delete or rename the nuvi's D3153090A.JCV to something like D3153090A.JCV.disabled.

Fire up the nuvi and take it for a drive or simulate a route that includes an interstate highway exit and compare the great junction view you have now to the poorer quality (or non-existent) junction view that was given to you earlier.

Note that all jcv files are linked to specific maps so when you perform your next map update in three months or so, you'll need to find, download and copy the large jcv file designed to work with the new map.

Thank you. I have about 870MB free space available on my secondary SD card.I'll try loading it there.

Would this large JCV file work on a Garmin Nuvi 50LM?

Well the big jcv file went onto my sd card. Some simulated routes found the file so I guess it's working OK.

If you deleted or renamed the old small jcv file on the nuvi and you're getting junction views, then all is well since the nuvi must be using the new jcv file. Well done.

Not advised

Thanks...

Since the 50 uses a split screen JV, trying this full-screen file is not a good idea. There may have been discussions earlier showing that the file doesn't even work on "Essential Series" of nuvis like yours although I be remembering some other issue. As long as you keep the original jcv file that came with your current map, you certainly could try the large jcv file if you wanted to. It'll either work or not work--and if it works, you'll either like it or not.

This large jcv file is used mostly by folks with much older nuvi models that use full-screen JV display but aren't offered the large file in a standard map update (the nuvi 8x5 series, for instance) and is also used by a small number of folks with nuvis that feature split screen JV but prefer to see a full-screen JV.

JCV work in Zumo 660?

I purchased a pair of Zumo 660's last fall with NO maps installed. Got an extraordinary price on the pair, but as I said, no maps. Just put a sd card with North America on them and they operate perfectly, with one exception. NO junction views at all. What is the current line of thinking regarding using the JCV file offered for the 8X5 from garmin in my 660? Thanks

JCV with SD card

If you purchased pre-installed City Navigator maps on SD, I don't think the junction views will work with it. I don't know this for sure, and it wouldn't hurt to give it a try. It will either work or it won't.

If you installed the City Navigator map to a SD card from a download or DVD, the JCV file should work with it, but then I think you should have received the JCV file with the install.

I tried using the JCV file furnished by Garmin to update the JCV file in the older map update to see if they might be interchangable. Apparently, they are not. The software garmin uses is pretty proprietary for each unit. Not much we can do as consumers and users...

Correct

You are correct. Each quarterly version of City Navigator NA has its own set of JCV files (depending upon your nuvi model) and any jcv file from one map version will not work with any other version. Once you start using the large jcv files, you will need to find, download and copy the correct jcv file to your nuvi with each map update.

It's possible that the large jcv file for your older version of City Navigator can still be found. Tell us what map version you're using and maybe someone can point you to the download of the correct large jcv file.

Large JCV Files

I called Garmin today and spoke with one of their Customer Service reps. He claimed Garmin Express will recognize what JCV file size is currently loaded to my Nuvi 1490LMT and update JCV files to match what is currently installed. Can anyone confirm this is correct ? I currently have large JCV files installed (my Nuvi 1490LMT has a 16GB microSD installed).

No.

Unless it is a feature they have added in a recent update, I think it is BS. It definitely didn't work that way on my 855 when I tested Express on CN NA 2013.40. I had the 2013.30 map and large JCV on SD for my 855. Express installed 2013.40 with the puny JCV.

As you suggested, I downloaded link to large JCV file...no problem.

Currently there are only (2) folders on my SD card...one named "Garmin" and one named "Map". Which folder do I copy the large JCV file to ?

I found the folder containing the small JCV file (25,137kb) in the .System folder that appears when I click on Garmin Nuvi icon/folder found on "My Computer" when my Nuvi is connected to my PC.

Why do you need to rename small file that came with mapset and what should it be renamed ?

I greatly appreciated your tech skills and patience with me.

Cruise:

Install the large JCV file in the Garmin folder on the card...The small JCV file inside the system file can be renamed .old or anything else.
I delete the small file on my Gps units.
