Interesting....my Verizon V710 and Treo 650 pairs well with the 2005 BT/Assist module and no hacks needed. Phone book transfers and Caller ID shows up and you can make calls from either the car's telephone menu, steering wheel, or voice recognition or from the Treo or V710. Maybe there is a newer firmware for your Samsung. The Visteon bluetooth module doesn't work with all BT phones either. Seems like the newer BT/Assist modules are more compatible with more BT devices.
