Thread: Transform a Nuvi 37xx in a Nuvi 34xx for dummies

No BTM folder in my unit (either 3790 or 37xx->34xx). Maybe Region dependant or more likely, mobile phone model dependant. I don't get phonebook either on my device (have 'older' LG phone) which may explain missing files.

006B121102.GCD (Touchpanel software version 1.23) This file has differences to the 006B121102.GCD posted for 37xx on other thread. Compared files in HexEdit. Maybe filed is 'tuned' to give accurancy on different production runs but seems silly if Garmin giving different files the same name.

Suspect \Audible is created only when loading an audio book.

006B139900.GCD could be the interesting one for HD receivers maybe?

[3760-->3490] I created one in .System and everytime I connect it to my PC, is empty.
When I first paired 3490 to my Galaxy S2, it asked for permission to access contacts and call history.
Then it transferred all my contacts and history to 3490, but when I connect to pc, BTM is still empty.
Second connection to Galaxy S2 and then after, it dosen't ask for permissions any more and my phonebook is already in 3490.
