I have a 2002 4.6is with the MKIII navigation stereo and DSP and wanted to know if anyone in my situation has successfully replaced the old with one of the new stereos with bluetooth built in. If so which one did you purchase, the approximate price of it, was it difficult to do and how is it working?
