[K Hamlet]

Same issues here is Ca. A wire is hooked up to the emergency brake switch. The video only works if the brake is set. Rear unit works all the time. I can pipe sound through speakers if I want to listen while traveling or the passenger can use headphones.

When my wife wants to spend some extra time in a store, no problem. I just go out to the car and catch some Osbornes (short time period) or a movie if some heavy duty shopping is going on.
