I'm picking up my Outie XLSon Monday and as I've posted here a couple of times now I'm looking at replacing the stock radio with an aftermarket navigation system (probably the Kenwood 8120).

My question is about how the bluetooth system is integrated with the radio. Is it part of the stock radio, i.e. I take out the stock radio and I lose the bluetooth capability, or is it a separate module that I could connect to the new nav system I buy? If anyone's done this I'd really appreciate the input because I need to know if I need to buy a whole new bluetooth module or not.

Thanks!
