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

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
The inventory is like this:

Boot BLK B0971-00 6.20 nuvi 1200 Boot Block Software PASS

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

D1340-50 is correct.
Your Basemap is quite old mine on 1300 is version 5.01 yours is only 2.00 (Off topic but you should upgrade it now)
Show us dir where you have your JCV files ?
Your nuvi is not seeing the JCV files in the Inventory

[Only registered and activated users can see links. ]

Both those locations are OK for JCV
Make sure you are not typing JVC instead of JCV lots of us make this mistake more than once. (check again)
JCV must show up in inventory. (Next line after Time Zone Map) (Check again inventory)

Even if the JCV is the incorrect one for your Map it will still show up in Inventory.

Sorry, the 'B' was a typo. The important thing is the suffix: '-50'. That means JCV is enabled as is SLI etc. Your original splash was D1350-00. There is NO JCV file listed between the Time Zone map and the Splash lines. It should show a line starting with 'JCV' and then further info. If it's not there in your Inventory then as dasilvarsa said the JCV file is not being recognised for some reason even though the file path is correct and it's actually enabled on the device. That only leaves the file. So if the JCV version matches the map version that it's teamed with and the file and folder are correctly named, then maybe the file itself is corrupt.

The final question is have you hard reset or cleared Non-volatile memory on your unit?
