Hello all. I recently picked up a 2006 2.0T Q6MT with less than 20k. I am planning on picking up a Garmin Nuvi 765t for all the traveling I do for work. I was hoping someone had info or experience on hardwiring the GPS system into the stock deck for use of MP3 and Bluetooth through the speakers. Any ideas or experience or other ways I should be thinking about going? Thanks!
