Folks, I'm shopping for a double din DVD player to toss into my 2006 Honda Pilot. My primary requirement is to be able to fully use my N900 with the radio, using bluetooth to play music and take calls.

What sort of radios have you found worked well with the N900 to make calls?

This is relevant to my interests.

Sony make economical automotive head units with full bluetooth compatibility. The models available are always changing, but the last one I had was about $100 US. It featured a built in mic and showed track information. I had track control at the head unit too.
