I had an old hardwired Nokia car kit in my 2003 SL with Bose. I just swapped it for a Parrot 3100 kit and I love it. Highly recommended. My Razr stays in my pocket and calls come in through the Bose. Fortunately my installer found an interface for the Nissan Bose that required no cutting of wires. My previous Nokia kit had to have an external speaker which was pretty weak. This new interface mutes the radio automatically and sends the sound through my Bose amp to the speakers. It sounds just great. I push the green button and say "Call Sheila". It is amazing. If anyone is looking for handsfree try the Parrot (even though it is made in France)
