HI I just got a 300te 1993. It has the built in phone. I see the large connecter in the console for the phe so can tap into it. However. the phone service is set up for verizon and I use cingular. Also my goal is to see how to use the hands free built ins with my cell phone and not to activate the car service, just ue the sound , built in mikes etc phrough my cell phone headset jack. Anybody ever solve this one? Thanks Marc
