stealth V1 in BMW
 

At last build my adapter from Valentine One to BMW E39 - Radar Detector Jammer Forum

I know this is not an E70 but it reminds me of the Stealth One units that worked in earlier X5s.

I'm not sure this would work for me especially if there are warranty issues. I leave Thursday for 3K miles that includes VA so I am trying out Excort's Redline since it is stealth compares well to V1 in several tests but, of course, no arrows. Then again I also have to go through ATL so lidar will be a major concern there.

I would not risk voiding my warranty.
