Nuvi 68 - large JCV problems with 2025.20
Tue, 11/26/2024 - 5:45pm
Hello everyone!
Updated Nuvi 68 to 2025.20 and got the large JCV file (D9673050A.jcv).
Unit connects fine to the PC in Mass Storage mode. File is in .SystemJCVD9673050A.jcv
Now, after simulating some travels, I don't seem to get any large junction views as I did previously. All the highway exits nearby used to pop them up, but I don't see them now.
Did I misplace the file? Do I need the smaller JCV file as well? Perhaps the exits are so simple to navigate that they removed the large views?
Any help or ideas are appreciated. Thanks!
We have a FAQ on this
The nuvi 68 cannot use the large Junction View file. Not only is the device hard-coded to only recognize split-screen junction views, it does not recognize photorealistic junction views - as found in the large JCV file - at all.
You need to be using the JCV file downloaded to the device from Garmin Express when you updated the map.

I did update the Nuvi 68 in Garmin Express, but I can't find any .JCV file anywhere in the folders. Maybe that explains why I don't even have th split-screen junction views?
.jcv file
The .jcv file is normally installed in a folder named JCV which is in the hidden .system folder. If you can't see the .system folder then you won't be able to find the .jcv files

Remove the Large JCV
Your map update should have installed the correct jcv file(s) so if you simply remove the manually-installed Large JCV file that won't work with your nuvi, you should see the split-screen JVs.
Here's the FAQ mentioned in this thread:

If you did find and delete the jcv files installed with the map update, you'll need to reinstall the map update.
I reinstalled the maps using
I reinstalled the maps using Garmin Express, Nuvi 68 works fine with routing and such, but I don't get any split-screens at all...
There are no files in the .System(slash)JCV folder...
I wonder what's going on here
Thanks for trying to help, Craig.
JCV
I thought I had a link for the proper JCV file. I don't.
Regarding your issue, the Nuvi 68, unless sorely mistaken, requires a MicroSD card to fit the map. The JCV file may be stored on the MicroSD as Garmin Express tends to ignore the internal storage when updating maps if it detects a MicroSD card.

As mentioned, your nuvi 68 likely needs a microSD card. Garmin’s recommendations seem to be vague or conflicting so I would suggest a class 10 32 GB card.

Vague and conflicting? Most definitely. In general, ANY Garmin with a MicroSD card slot will accept up to a 32GB MicroSD card, regardless of what Garmin mentions in its help documents. Garmin does specifically note the current DriveSmart units can accept a 128GB card, but at this moment what device requires such a large card?

Are you sure? I don't have a MicroSD card in the Nuvi 68 and there is some free space left...
I might try it, maybe it's going to make the split-screen views reappear
Thanks all for helping me out on this.

Having a bit of free space on the device itself does not mean you can install a file, especially if the file size exceeds the available free space on the device. To be honest, I think you are likely long past needing the memory card. Even my nuvi 265 from 20 years ago needs a memory card to properly update maps.

I just added a 64 GB microSD card, and tried to reinstall the maps using Garmin Express.
The device still has 1.7 GB free space, and did not offer to reinstall the maps on the card.
I'm not giving up... does anyone else have a Nuvi 68 lying around that could validate if their split-screen .JCV file is in the hidden system folder?
Check the format

Check the format of the memory card. It needs to be FAT32 and a 64GB out of the box isn’t likely to be FAT32. More likely exFAT.
Just as a point of interest, a few people here recommended 32GB. Why did you get 64?
