Hello so I have a 2006 GTI with the base stereo option that only has AM/FM/CD Changer/Satellite Radio. I would like to add Bluetooth functionality for making and receiving calls, and streaming music. After spending a couple of hours doing research I m thoroughly confused about what the best and most affordable option would be for me. I would like 1.) to keep the car looking as OEM looking as possible 2.) be able to use my steering wheel buttons. Other than that I'm not too concerned with having access to a phonebook from my display or seeing information about calls/music on my display. Should I buy a newer stereo/receiver? Would that be compatible with all the wiring in my car? Is there a way to replace my satellite radio button with Bluetooth functionality? I never use it. I am open to any suggestions. I have installed new head units before and I'm confident doing this myself but I lack very detailed technical knowledge about what exactly would be the best option for me here. Thank you!!!
