1) track info maybe possible, but maybe a customize thing. I've heard SE walkman phone display track info on SE A2DP headset like the DS970, not confirm though

2) I also recommended the Parrot MK6100, I've one and it rock. with the A2DP you can even route GPS navigation voice prompt/instruction through the car stereo (with 2 minor issues, the unit does not switch over fast enough so lose about 0.2 seconds in the begining, so need customized voice files to compensate, and after the voice prompt finish, take about 1-2 seconds before the Parrot unit release the system back to the car's deck/HU)


Parrot kit is especially good for those of us with newer car that do not have a standard aftermarket Headunit interface, or for those of us who want to keep the stock as much stock/OEM as possible.
