Bluetooth Head Unit/Audio Streaming

[sheep]

I'm looking into a head unit with Bluetooth audio straming (Think its called A2DP), as I have a walkman phone which I use as my MP3 player. There are a couple out there now, but not much info to go with them.

Sony do one, BT5000, but you can only search through tracks, not playlists or albulms, which is a bit naff if you have 1000 songs.

Anyone know of a unit which lets you search playlists like you can if it was wired up to an ipod?

there is a parrot handsfree kit which does it so you can buy whatever radio you want
