I bought my BMW56CAN from TVNAV2GO out of New York for $400. It is also a newer version than NAV-TV's. It has PIP for our 8.8 Screens. If you couple the CAN with NAV-TV's VehicleDock, you can play videos off your IPOD and control the IPOD thru the I-Drive and steering wheel.

See my thread:

You can also find the CAN's at Alibaba.com for as low as $290 but be very weary of the source ... lots of scammers.
