Hey everyone! I have a 2002 GTI and I want to get a bluetooth receiver for my stereo but the stock deck doesn't have a 3.5mm headphone jack, but there is a panel in the trunk of the car that has wiring for sound. I'm not sure if they are for amps or a disk changer. I haven't checked the manual yet, but does anyone have a bluetooth setup for their MKIV that still has the stock deck. Thanks!
