I haven't installed my carpc yet and still debating if I will do the backup camera since I might be parting out the car to get the new vette which means I'll be selling my CF CSL trunk.
So if anyone wants this I'll offer it up for sale. It's the nav2go unit + backup camera for the e90/e92 + iphone/ipod video connectors + mobile HD TV antannae (not shown but requires hauppage or tv tuner and carpc).
This unit allows you to have multiple video sources play on your OEM navigation screen. People use it to connect a backup camera, forward camera, night vision, carpc, gaming system, TV, etc to your OEM navi screen.
I'll request to have the post removed if I install it, but for now it is for sale.
Asking $250 for the whole set.
