Thread: Nuvi765t installing Mapsource CNNANT2011.31 questions

If you unlocked the CN in Mapsource according to your device id, then it should be unlocked in the 765. (I am not sure whether your current firmware expects already the new gma-protection)
If not, then the message comes most likely form the gmap3d.img.
Just create a gmap3d.unl file and paste there inside the unlock code

Do I just use the same unlock code for the gmap3d unlock file as the one for the CNNANT2011.21 or do I need to generate a different code somehow ?

Thanks
