Thread: Enable features in your nuvi 12xx, 13xx and 14xx - JCV, LA, TTS

First of all thanks for your time to help, much appreciated.
I just checked again, and I can report that I can see the greyed out 'Junction View' with or without the JCV folder.
I have also tried to move the JCV folder to the Garmin folder, but the same crash happened.
I'll try to test with other maps with junction view, which I don't have any other at the moment.
By the way, I have no knowledge of getting any JCV with 'lower resolution'. Do you have any hint on that?

I also attach my Inventory list here, hope this helps.

Your inventory looks fine, to my knowledge, it is just as it is supposed to be. (all tests passed, splash verion is 1340-50. I'm just missing the JCV item -should be just above Splash item. Probably, this was because you didn't have a JCV file in your device during inventory inspection).
I noticed, that you're using a Hong Kong map as gmapprom.img. Try removing this file (simply by renaming it to e.g. gmapprom_._img - look for it in ".System" folder). Maybe this helps, if your JCV is in conflict with primary map.
Put the JCV file into device and repeat the inventory inpection. There should appear the JCV item, showing its version and on the right side, there should be remark: "Working".
In CN Europe 2011.40 (which I use) check the following: [Only registered and activated users can see links. ]
In the post, you can find three versions of JCV file. All are matched with CN Europe 2011.40, but differ in resolution. In my device (nuvi 1350, flashed during 4.90 SWV, after update to SWV 5.00 everything continues to work normally) all three files are OK, but the quality of JCV images differs.

P.S. How is working your Lane assist function? Originally, in nüvi 1300 it is not available, it shoud be available now.
