Thanks for the fast response guys!

I have heard of the invimirror thing and I think I might get that. How much do you think it would run to have Mercedes (100 bucks per labor hour) install the mirror and conceal the V1?

The overall goal is to have no wires anywhere visible.

Anyone have pics of this in their cars? How do you run the wire from the main Valentine unit to the mirror in an E500?

I read something on these forums about tapping into an aux. fusebox on the drivers side to hardwire detectors.
