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

I don't have any problems with the 1300. All the features work, including junction view. I simply do not receive a junction view file with the map when the map updates, and even if I did it would be replaced by the Garmin-provided full JCV file. Garmin skimped on the memory for these units in the US as I'm sure most of us are aware, and Garmin provides the full file for direct download from its servers as a response to repeated complaints about lost junction views.

I do not know about this bug! I did not have such problem still...

Of course you didn't. European and Asian units presumably have additional memory and features not found in the US units. In the US, 1xxx devices have 2GB of internal storage which is no longer sufficient to store the entire map of the United States or North America. Devices like the 1350 and 1390 added Junction View, but those devices are now getting 50MB Junction View files on downloading a map update because of the space constraints.

For me at least, the fact I don't automatically receive a Junction View file when I update a map isn't a problem. I'd rather have the 700MB+ junction view file with its 60,000 images versus a 50MB file with perhaps a tenth that amount.

I have some US LMT device too. But I am use this forum tricks for it without problem...

@Kova78
You have the large JCV file which should work fine in your 1200, the feature is enabled and the file path is correct for the unit. You can also put it in a JCV folder in the microSD's Garmin folder. However, nowhere all major junctions/exits have a JCV associated with them. You will have to find them on a route.

Try a simulated route from or to any major city using a major arterial multi-lane motorway, scroll thru the route and when you see the words 'Junction View' light up at the base of the screen, press then and you'll see the junction view.

Thank you Neil for your response
I tried to simulate a route, but nothing happened!
I used one of the major route, highway of my country! It seems that the JCV feature is not enable on my GPS!
I tried to put the file in the SD:\Garmin\JCV folder, without success!
I tried also the low-res JCV file (D3084110A)...no luck!
:-(
Help!
Thank you


P.S.
I'm reading the entire thread, I noticed that in my Inventory section the JCV is not displayed (see post #70 and #71) :°

In your Inventory [same page as displayed in Post #70] does it show 'B1340-50' beside 'Splash'? It must do, because the JCV path is now in your GarminDevice.xml so therefore JCV is enabled and the problem is elsewhere.

NO it shown as D1340-50 2.00

I tried to delete the file mlg_history.db presents in the .System/sqlite folder in order to update again from Webupdater...nothing happened (I did 3, 4 times).
And after I tried to upgrade from the normal procedure (not SD) and again..nothing happened (I also noticed that Windows didn't delete the hidden file GUPDATE.GCD, so I used Linux to delete it).

I think that the problem started from the first time that I tried to update via SD method with the 5.20 FW version, what do you think?
Is it possible to reverse the process and start again from the scratch :D?

Thank you.
Bye
