means :Upgrading MapSource to a the latest Garmin original version will NOT remove any of your unlock keys.
We use a patched Mapsource version, not the original one, some months ago, Garmin introduced the new GMA policy, you can unlock maps with jetmouse kg in a patched MS , it will work, but it wont work for IMGs sent to gps coz new firmwares ask for the .gma file .
No ,by Garmin new firmwares checking and looking for .gmaThe problem is that all maps having a MapID >= 2200 will get the "Unauthenticated" status.
They will get? How? By the Saint Spirit apparition?

Now it makes more sense. Solution: just use the stock mapsource software and unlock with the usual 25-letters unlocker.

Several questions:
1)Is there a way to look inside the JVC file to see if it is for the 1xxx series or some other series?
2)is there a JVC file that works for the .40 for 1xxx nuvi?
3)If you used mapsource I dont believe exporting from mapsource to .img ever gives you a jvc file. So how do people who use mapsource get junction view then?
4)Where do I place the time zone img file?
JCV file works for all nuvi supporting JCV.
Here is jcv file [Only registered and activated users can see links. ]
Gmaptz.img(time zone file) go in hiden folder .System.
Original nuvi dont support jcv you must flash to support Jcv.

ah so even though i got the 1450 nuvi it doesnt support JCV files out of the box. But flashing the firmware to this 3rd party one allows me to add JCV files so that junction view works with files?

Will this 3rd party firmware allow me to use the high-resolution JCV views that the original 1450 wouldnt do?
