It is quite simple if you have the phone prep. Do you have the little mouth on your steering wheel, left side? If so you just find a TCU that was built '05 or later I believe. I bought mine on eBay. I took the old one out and installed the new one. There's a code on the TCU that you need to pair your phone. Mine worked like a champ.
Sorry but no streaming music. It's phone only.
Good luck
