Just bought a 1999 740 and I can't receive incoming calls. Took it to the dealer and was told the phone didn't match the car; therefor not covered under warranty. I have a CMT5000VR owners manual so I guess that's the phone I have. The PSE box is wired tied to the bracket. Think maybe the previous owner/dealer took the good phone and replaced it with the one I have? The car was mfgd. 11/98. The PSE box and handset do match. It's the wire tie that concerns me. Dealer says it should be a CMT6000. Any help?
