I have a 2004 E320, I had TeleAid until the change from Analog to digital. The upgrade was not worth the cost to change. I never activated the phone, V60 phone was obsolete before the car left the lot. However, with the new hands free laws I would like to activate the phone options of the car. What components do I need to have the steering wheel buttons work. I also want to install bluetooth to work with a blackberry.
