Hello to everybody. I am a new Garmin 3760 user and I am trying to install NA 2012.30 maps on SD card. I'd like to know which is the best 'folder' structure to create and where to put different files. I've currently downloaded unlocked img files. Here are my doubts:
1)Should img files (gmap3d.img, gmapprom.img, gmaptz.img) copied into <SD root>/Map directory?
2)Which are the proper JCV files for 3760 unit?
3)Where should JVCs files be copied to?
4)Where should *.db and *.sid files be copied to?
5)ASR shouldn't be required since are supported by 34xx devices only. Correct?

Many thanks in advance for your kind help!
