Would it be possible to give me an explanation of how you did this without draining the battery?
- DId you find a reverse signal that you could plug into the head unit?
- Do you use the reverse light to power and turn on the camera?
- Did you get the guide lines to function?
- Are you using the memory feature that requires constant power? If so, how did you do that? If not, is the power drain the reason you didn't?
