I have a 2003 Boxster with the Becker CDR-23 head unit and Bose amplifer and speakers. I'm thinking of replacing the head unit with an aftermarket one in order to hardwire my iPod (I hate the FM transmitters), but am not sure if the Bose setup will allow this.
Has anyone done a similar swap, or know what the connection is between the CDR-23 and the Bose amplifier (e.g., RCA, proprietary...)?
