i bought the garmin nuvi 3790 for my 08 e92. installed the bmw installation and mounting kit myself. i brought the car to work to program/code for the navi so the sound can come out through speakers(i work for bmw).
after everything is done... no sound comes out through speakers. i found out that the bmw branded nuvi 3790 have a option you can select for vehicle speakers and the garmin branded 3790 dont have that feature. sucks..... i guess i gotta contact garmin to ask if there is a software i can get to convert it for the nuvi itself
