it's probably not the car... Cell phone company are trying to limit what you can do with blue tooth mostly because they don't want you...the customer...to be able to download data from you computer such as mp3's, ringtones, address book etc for free... they want you to pay extra for it and dowload data from them(or via) to increase their revenues... So they demand that phone manufacturers limit the bluetooth features in their software. It is becoming a real problem... some phone company are better than other. Cingular is the best verizon and sprint the worst.
