http://www.streetdeck.comThis is the supposed do-everything deck that integrates GPS/Nav, MP3, CD, DVD Player, Video PLayer, Car-Diagnostics, Picture viewing, bluetooth phone, WiFi, USB, etc...
They don't seem to support an ipod conenction though (for real-time playing and access to the iPod's DB/content - they might be able to sync with the iPod's normal USB connection)
It's all tied together with decent-looking software. Looks like there would still be some significant integration and configuration work involved.
