I am returning my E39 528iT back to stock before I sell it to the next user. I have a StealthOne available from that car if you are interested.
If you have an E39 and a Valentine One Radar Detector - then you need the StealthOne. It reroutes the display from the Radar Detector Display to the OBC on your cluster. It hides / masks the V1 from being seen from behind due to lights. If you live in VA this is a must for using the V1.
$200 OBO. PM me here or [email protected]
