Junction View - Use it or Lose it?

Create route just north of Atlanda GA on I-75, end the route south of Atlanta GA on I-75, There's junction views on this route.

No junction views on I-75.
I renamed the original JCV file .xxx.
Should I have left it or should I delete it?

Here is a really short route which should produce 1 view:

Start: N34 04.052, W117 58.954
End: N34 03.606, W118 00.085

This is in Southern California.

This one is short enough that you can run a quick simulation. Put the Nuvi in simulation mode and then enter the start co-ordinate under Where To and set that as your new location. Now do a Where To - Coordinate and enter the End co-ordinate as your destination. Say Yes when the Nuvi asks if you want to simulate this route.

I'm wondering if your problem is looking for the junction view button to light up instead of actually driving/simulating the route.

Also, here is a much longer route (about 10 minutes to simulate) which produces 5 views using the 243000KB JCV file included in the 2012.10 update for the 3790. You may want to try this one as well:

Start - 3401 Dufferin St, North York ON (use Canada - Ontario - Search All to enter this address. You want the one with Postal Code M6A

Set that address as your location (set location)

Finish - Where To - Points of Interest - Transit - Air Transportation and select Pierson Lester B Pearson International Airport. There are multiple entries but any of them will do.

You may want to leave the original file, I'm using a Garmin 2350LMT, I have 2 JCV files, the original file of 105 MB and the recent upgrade added a 99 MB JCV file. I now have 2 versions of junction view, the old image of the junction view appears and now the more realistic view on some junction locations.

I drove the simulated route in both directions. Lane Assist works, but not Junction View. Why does Garmin simulate routes at such absurdly slow speeds?

@ ScottK1968

You may want to rename the older file to see if there is any difference on your 2350. If your looking at views in the US, all of the PhotoReal ones are coming from the newer file. Since all views are not currently converted to the new format I think your going to see those 'old images' on some junction views, whether the old JCV file is on your Nuvi or not.

Renaming it to .jcv.old will allow you to tell for sure if you need it any more. The map update should have deleted the old file but Garmin has had all kinds of trouble with this in the past.

I added another one to my original post you may want to try.

The simulation for the most part uses posted road speeds. The problem I have is that unlike other GPS makers, Garmin doesn't let you speed up the simulation.

Thank you for the advice.

I have been having a quick look on the Tom Tom section of this board and it seems that they do not seem to have these map update / lack of memory problems that we have, or is it just me not finding the right thread?

When you say "downloaded the 83MB JCV file" do you mean you did a map update?

What is the name of the JCV file, and which level of maps are you using?

My 1490 with 2012.10 maps displays junction views for @ScottK1968's and @t923347's sample routes.

I have a 760 and never knew if the Junction View feature was worth upgrading to. I'm still not convinced yet but that's mainly because I haven't run into many situations where it was necessary.

Don't have the latest TomTom to check but on my 540 it actually came with less free space than my 1490. Out of the box the TomTom had 97MB of free space on a 2gb drive while the Nuvi 1490 had 128Mb free on the same 2Gb storage.

Maybe the TomTom doesn't have these lack of space problems because they don't have as big a map file (less coverage?) or as many Junction View pictures. On the other hand they could use a different file compression system and cram more data into smaller files.

As I stated earlier, I found this feature very useful while driving into the Golden Glades Interchange (I 95/Florida's Turnpike/US-441/Palmetto Expressway/SR 9) in Miami recently.

It had been years since I went through there and junction view for me worked like a charm. They really help if you have to encounter an unfamiliar "malfunction junction" interchange.

Yes, a simple on/off toggle would help for those who want to decide for themselves if they want/don't want to see the Junction View. Unfortunately, Garmin doesn't seem to think the say way.

While is is not as convenient, could someone not "toggle" the .jcv file on or off by changing the extension to, say, .jxx?

I prefer the standard 2D, top-down view personally.

If the system can't find the file because of a wrong extension then it can't use it.

I too would like to see an easy option to disable junction view. I find, when it pops up, that I start looking at it instead of the generally easy-to-read signs posted above and around the interchange, as well as the lanes and traffic.

So, to me, it is a distraction.

Great! Now I just need to find the file...lol

Is there a way to get just the junction view from Garmin?

If your GPS is still a nuvi 780, you will have no jcv file and if added, your nuvi won't use it.

I do not have map updates. I downloaded the JCV file from Garmin and placed it in the JCV folder.

Is junction view built into the software and can only run on certain software? I have a garmin nuvi 265 and was wondering if i were to add the junction view file to the unit, would i be able to use the function?

Well,

I deleted the 83MB D3191000A.JCV and restored the 48MB D1279060A.JCV. I now get a Junction View at I10 and I605.

Oddly I also get a second Junction View at the split of I605S and Freeway North on my 1450, which has an older and smaller JCV, 36.6MB D1279020A.JCV.

That leads me to believe that the JCV files are linked to specific map versions.

My 1450 has NT 2010.10 and D1279020A.JCV
My 1490 has NT 2011.10 and D3191000A.JCV

I don't understand why the smaller, older file shows 2 Junctions and the newer, larger file shows only 1.

I was under the impression that Lane Assist is the highlighted or not-highlighted arrows at the top of the screen before a turn, and Junction View is the full screen view of the next interchange, complete with the big green signs overhead.

However, when viewing the turn by turn directions during a route (where it lists the next turns in order complete with a mini-map of the turn), there is a button labeled "Lane Assist." When you press the Lane Assist button, you get the full screen view of the next interchange presented.

Why the inconsistency?

I suppose the number of Junctions depends on the size of the JCV file. I don't understand why the smaller file seems to have more junctions. I'm disappointed that the large file didn't work on my 1490.

I have noticed here in Illinois, that they have been beginning to paint the road ID right on the pavement and seems to me to be a big help, you can't miss it, unless of course, your in bumper to bumper traffic, which never occurs here in Illinois....

Yes gdfaini, the map and JCV files are paired together, as far as I know.

My 1490 came with 2011.10 maps and D1279060A.JCV (47MB)

I did two custom map installs:
2012.10 (Canada only) used D3178000A.JCV (45MB)
2012.10 (US and Canada) used D3153020A.JCV (45MB)
Even though the sizes were identical, the JCV files were physically different, with unknown differences.

I've read that when 2012.10 first released, it came with a 358MB D3060020A.JCV file. Now only the 45MB file is available.

The 83MB D3191000A.JCV file available from the Garmin Support site was for the 2011.40 maps

Looks like we have to wait for the next map update to find out whether Garmin has a solution to these jcv problem.

On the first attempt to get update 2012.1 I received the 367MB file. This was using GarminMapUpdater v2.6.11. I backed up the unit to DVD.

After this update Garmin switched to GarminMapUpdater v2.6.12 and now is at v2.6.15. There seems to be no check as to how much memory is available on the unit, only the 46MB file is received.

A check on how the two files compare, I ran two tests. One from DFW to Caribou, Me. another from DFW to Edmonton, AB. The large file shows 17 junctions to Caribou. The small file shows 8 junctions. From DFW to Edmonton the large file shows 5 junctions, the small file shows 1.

There doesn't seem to be any attempt to change the Map Updater file. If Garmin doesn't allow the program to recognize an SD card, I guess we are screwed.

There seems to be disagreement as to whether maps and JCV files are tied together. jjen was test two different sizes

but WAASup says

Can we use different JCV files or not?

I guess that means I'm stuck with small JCV files for my 2010.1 and 2011.1 maps.

My 1490 is only about a month old. What are the latest maps? Seems like I should request a free map update from Garmin if 2012 maps are out.

The GPS I bought in May has 2011.1 maps. 2012.1 was out by then. Should I ask for the 2012 map DVD or is it too buggy?

Like all Nuvi devices you are eligible for one free map update if one becomes available within 90 days of the GPS first obtaining a satellite lock. From the Garmin website:

"Get the newest maps available and navigate with confidence with our nüMaps Guarantee. Simply connect your new Garmin nüvi, dēzl or zūmo to your computer and visit www.garmin.com/mapupdates within 90 days of first acquiring satellites while driving with your device and you'll be able to see if a free map update is available. With our nüMaps Guarantee, you'll be up-to-date when you hit the road."

Did you buy the 1490 new? If not you may not be eligible for a free update. Garmin's newMaps Guarantee is only eligible on new or factory refurbished devices.

You'd have to check with Garmin but I'm not sure that the free update is available on DVD. It may be only a download. Not sure.

Thanks. I'll do that tonight. I thought I'd have to call Garmin customer support. I don't have highspeed, so will have to request the DVD (I checked and it is available).

jjen was using two JCV files for the same map (2012.10). It's possible to have more than one JCV file for a map update.

You can't mix and match JCV files with maps that they weren't intended for. For example,you cannot use a JCV file that came with the 2011.40 download for the 2012.10 map. You must use a JCV file that came with the 2012.10 download.

Does this clear things up for you?

You have 90 days from when you first powered on the GPS to get the free 2012.10 map update.

It is only available as a download from the Garmin site (no free DVD).

EDIT: You need to register your GPS at garmin.com if you haven't already. Select "Product Registration" from the Support drop-down

After registration, the map update will be available from https://my.garmin.com/mygarmin/customers/myMapsHome.htm

I ordered the free 2012 DVD for my 1490. ($10 shipping).

Bummed to see I could have gotten a free 2011 update for my 1450 if I had checked in time. Oh well. We don't use that one for long distance travel anyway.

Thanks for reminding me of that policy. I'll have to remember to register my GPSrs sooner in the future.

I am glad I have it and use it a lot. I wouldn't considera GPS without this feature.

The trick is that it is within 90 days of "satellite lock" NOT from registration

if I had registered it quickly it would have reminded me of the free update. I didn't remember to register my 1450 yesterday. It's well over a year old.

I've been using a Navigon 8100T for the last 3 years and their version of "Junction View" worked flawlessly since day 1 and no matter where I was. I currently have a Garmin 3970T and JV is a ghost. I live in the NY/NJ Metro area and travel up and down the Garden State Parkway & NJ Turnpike and JV NEVER happens. Oddly enough one day last week I was on a trip to New City NY and JV actually came on! On a highway in no mans land it came on.

I am currently using City Navigator North America NT 2012.10 - Map+3D+JV(G&N)+HT, Apr 11

I do have an up date available but here's another story! I purchased from 6th Ave Electronics on 6/8/11 and also registered that day. When I called Garmin to tell them how displeased I was with the unit and why do I need to pay for a map update? Well, it seems somehow the unit made satellite contact prior which put me out of the 90 days for the free map update. I did fax my reciept so I should be able to download later today.

FYI, my JCV file is D3191010A.JCV @ 237 MB.

Man I miss my 8100t!

I live in Chicago and just drove to Utah and back and ALL the turns had Junction views. I love the feature.

My 2460 has a ~450MB JV file.

Riding around Atlanta it always comes up where I'd expect it to and sometimes it surprises me by coming up where I'd think, "Wow, they even got this intersection/interchange?"

I like it but mainly because it's a split screen on my unit. About 40% of the screen is JV and the rest is the regular map with the lane assist present. I like that. I can see either one and they're both helpful.

In the NY area I get it a few times and like the way it comes up. Quick way to ensure you'll getting onto the correct lanes.

I use many Garmin models with junction view regularly, as I work for Garmin. From a purely factual point of view, Garmin has tripled the amount of JCV locations in the last map update and adjusted the format so that the map view moves to half screen and shows the JCV. This way you can still see your map and have the benefit of viewing the street signs too.

From a personal use standpoint, i have used in area of unfamiliarity and found it very helpful. In areas I know, I just let it run and look at the device when I need it.

as you can read in several other threads the natives are restless over the decision to provide a full set of junction view locations on only the newest models. you can take that information back to the marketing department and inform them this decision is ruining their reputation as a customer friendly company. many of us use models that have been discontinued and like the feature sets found on them. the newer models all seem to have subsets of the features many of us use virtually every time we turn on our units and subscribed to the lifetime map updates for that reason.

In this user's opinion there is no reason to purchase one of the higher end units because it may have some feature when we realize the extra investments in optional accessories such as maps or traffic services are likely to be discontinued as soon as the model is marked discontinued.

additional strikes against the company are the poor quality of software being released. this is evident in the lifetime map updater program which went through 2 revisions, if not 3 before this last map release, the many reported failures in unit software and generally poor perceived quality of the units themselves. Garmin may be feeling pressure from other vendors such as smartphones, Tom-Tom and inexpensive PNDs. at the rate the company is going, there will be no new Garmin for me, when it comes time to replace it will be with some cheap inexpensive knock-off that is essentially a throw-away. When the maps get outdated or the unit experiences a failure, it will be less expensive to purchase a new unit than update the existing.

The backlash from the automotive PND marketplace will be felt in the company's other lines as well. If a consumer can't have confidence in one line, why should they have confidence in another?

If you're a Garmin employee, could you tell me why older nuvi models, such as the 765t and 885t, that use Junction View are receiving a much smaller file with significantly less Junction Views than the newer models? Why can't the older models be made to support the split screen Junction View? Then the file junction view file wouldn't have to be so large.

More nonsense:

Q-Escalation from KANA On Demand Self Service Subject: JCV map update
2012.20 765T

Message: I was going to finally update the maps on my 765T but I have read on many forums that the JCV file was significantly reduced in capability with the 2012.20 uopdate. Can you advise if or when this will be rectified?

A- From: Product.Support@garmin.com

Thank you for contacting Garmin International.

With the map and junction view sizes growing, it must be limited with the device you have. Unfortunately, I'm not sure if this is something that will be changed in the future. The size of the file will depend on the type of device you have. I apologize for any inconvenience.

Please let me know if you have any other questions.
