Sorry if answered elsewhere, but here is my issue: If I am driving, I will usually have Pandora playing through the headphone jack to the Auxiliary hookup on my car's stereo. The car is also hooked up to the phone via Bluetooth in-car system. When calls would come in on my now replaced Palm Pre, it would automatically pause Pandora and the call would come through via the Bluetooth connection. However, with my Samsung Galaxy S, I note that phone calls are being treated like I have a plug-in headphone jack - requiring me to unplug the jack in order to hear the call (obviously, something I don't want to be fumbling with while driving). This also occurs if I try to make an outgoing call - the call goes through, but there is no sound until I unplug the headphone jack. Any solutions? Is there a way to make the phone understand the call should be automatically routed to Bluetooth? Thanks!
