Just bought a 2010 touareg tdi. Base model - no navigation. Basic sound system. Other than CD's there is no way to play your own music. My wife isn'y happy. She would like to be able play music via her iPhone. There is no jack to connect media and the Bluetooth for the phone doesn't support streaming music. After some reading on this site it appears this model has the 9W3 Bluetooth. My question is, should I look at switching out the Bluetooth box for a 9W2 unit? Would this work? I see Bluetooth boxes for sale on ebay. How would I know which part number to order. Would this simply be a matter of unplugging one box and installing the other? I do have a vagcom if something needs to be recoded. Thanks in advance for any advice. Want to make the wife happy!
