I need help identifying the correct phone for my car, which was purchased with the phone absent. The car is AH 60536, built on January 15, 2001. Included in the owners manual folder was an instruction pamphlet which identifies the phone as a CPT 7000, which I haven never seen seen listed on EBAY. I recently purchased a Motorola BMW-branded Star Tac 7797, which I hoped might be compatible, but to my chagrin it doesn't fit in the onboard charging dock. Is the CPT 7000 the only phone that will work? This is actually the second phone I have bought, to no avail- I should have come to the forum and gotten the correct information from the get-go!
