Unfortunately the only way to remove the music from your radio is with a dealer scan tool and usb memory stick. The use of the dealer scan tool is the only way to make the radio download songs on to the memory stick. Once on the memory stick they could then be uploaded to your new radio. Expect to pay a dealer about $100 for this service.
no i did not want to BUY one - but when asked this question at the dealership no -one seemed to haev the answer so I wanted to be specific as to what I was telling them they needed to remove my music - I still would like a parts number or How the scann tool is used so that I can get them to get my music off the hard drive
