teelow Posted August 25, 2010 Report Share Posted August 25, 2010 Hello all. I just purchased an X920BT and plan to install it later this week. I understand the function of the VSS wire for the navigation system and plan to connect it. I can't see any real purpose for the reverse wire, since I am not planning to install a rear-view camera. Does the reverse wire perform any other function, or can I save myself some time and effort and safely leave it disconnected? Quote Link to post Share on other sites
