I have been unable to connect any of 3 Cellphones to my newish 2012 C300 with the Premuim package. At first, my old phone, a rare brand -UT Starcom, would be recognized, but not connect. Neither would my Wife's HTC Aria smartphone - it was connecting but not functioning. Now, my new Kyocera (a non-smartphone with bluetooth) simply cannot be recognized by the Car. I followed all the arcane instructions, etc., but nothing works. The HTC connects fine with a Lexus RX. Have others experienced this lack of compatibility, or is this car an Apple Fanboi only?
