Thread: MapSource software version 6.16.3 + Patched release

Good evening

Thank you for your help.
I still have the same problem despite your advice.

1 - On the PC, deleting code in mapsource regedit

2 - With IMG 1.2 Unlocker v 1.2, file gmapsupp_lock converted (if I use v1.3 or v1.4, the gmapsupp disappears??)

3 - Copy of gmapsupp_lock on GPS but not visible

4 - Copy of gmapsupp_lock renamed gmapsupp with or without gmapsupp.inl, still "can not authenticate maps" to the screen.

Your help is essential.
Thank you

Edit: Installing an older firmware on the GPS unprotected GMA has solved the problem.
