Bluetooth AVRCP only device Is there a Bluetooth device I can use with my Android phone which has nothing more than previous, play/pause, and next track buttons?

There are many AVRCP Bluetooth devices, but they are all also A2DP sinks, which I do not want &ndash; I plug my phone's headphone output into my car's aux input.

Ideally, I'd like something I can mount to the steering wheel so I can change tracks without trying to find the button on my touchscreen.

Alternatively, could I buy a small A2DP/AVRCP device like this and configure Android to not send audio, but still respond to the track controls?
The Sony LiveView may fit the bill.
