I would buy a deck also. In my car i got a panasonic cq-dmr 993d headunit that is only available in japan. It can be feeded with DVD, MP3-CDs and MDLP2. I dont think i would by a sony headunit because i had several sony headunits in my car and i was allways disappointed by the sound quality. I would appreciate a Sony headunit because maybe after a certain time panasonic would offer a hi-md unit too...
