I just bought a Parrot Bluetooth MKi9100. Works through the speakers. Best Buy says they will install for $129.00 which doesn't seem bad at all but I usually do everything myself. I just don't want to short a power source that leads to the computer or something worse. I'm a long time GM guy so that is what I'm more familier with. I admit that I know nothing about the Touareg. Sounds like I answered my own question but what do you more experienced Touareg owners think?
