Funny how long it's been since we've heard much about cars or car add-ons using the Bluetooth SIM Access Profile but soon select Mercedes Benzes will be available with the Telephone Module with Bluetooth, utizilizing SAP. (Remember that other German auto manufacturer that used it
?) The system, which either comes tucked away in standalone box, or as an in-armrest handset option includes a SIM card reader and external GSM antenna uplink, so you can take advantage of higher powered cellular transmissions and get better reception than your phone could otherwise provide. Yours in a Benzo for €373 or €406 ($466 or 510 US).
