The '03 Vanquish has a Linn audio system with 6-disc cd player in the trunk; the cd is an Alpine product. I'm looking for a way to add bluetooth integration without replacing the existing deck. I'm very happy with the sound, don't have much need for the cd, and I'd like to retain the look & feel of the stock stereo. My thought was to break into the wiring to the CD changer and add something to integrate a bluetooth connection, including a microphone, so I can have hands-free calling and, much more importantly, access to the music & podcasts stored on my phone.
