Assuming you can control the phone via bluetooth, could you emulate the 'handsfree/headset' profile on the empeg, using the mic in to turn it into a universal bluetooth handsfree kit.

You would get into the car, set your phone to blutooth mode, and then when the phone rings, the empeg mutes, the phone hands the call to the empeg, which using the digital voice stream from the bluetooth module outputs it through it's DA. Meanwhile, the Empeg's Mic input AD'd and sent back along the bluetooth connection to the phone.

Assuming you have got the bluetooth chip talking to the empeg, it would just require the correct protocol to initiate a voice link rather than a data link.

In principle, it would be possible but the Bluetooth chip I have only supports data link (not voice link) and I only have VCC, RX, TX and GND pins connected to empeg. Even connecting those pins was rather challenging as you need to work with SMD components.

It might even be possible for the phone to send the CLID to the empeg, so the name/number was displayed on the screen before you answer it.

Well, that I've had for couple of months now . In addition, it periodically establishes Internet connection through GPRS to transmit the car's location information to a web page and gets latest traffic report around the major roads I drive.
