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?

You do not need to hook it up. No purpose really. THey say youre suppose to no matter what so the unit knows youre going in reverse however how long are you in reverse for lol!
