I see where it seems as if I'm taking it a bit far. I'm using the remote escort units in both of my other vehicles which I love. It's just this S1 with all of the features that goes with our X5 that I can't pass up so easily. It's too bad that the S1 wouldn't interface with Escorts remote unit or that V1 wouldn't make a remote unit.

Headrest install pics.. I'll have to do a search for that. Why would you lose laser capability with a headrest install?

Thinking out loud; my 4.8 is an 04 model and in the headliner behind the huge sunroof in the center is a lump; looks like a great place for a V1 but I'm almost positive that this is for the sunroofs motor. Can anyone verify this? How much room is there inside that headliner?
