THe stereo knows when the vehicle is in reverse when you hook up the reverse sensing wire from your head unit to the reverse lights in the vehicle. If you power the camera from the ACC switched wire, you can flip on the camera any time from the camera button on your head unit.

Here is a shortcut for you.... if you have a truck with a towing package, you can pick up 12V switched from your trailer plug. This will save you from running a power wire all the way to the front. Keep in mind..... It has to be a full tow package. The little 4 pin plug that you see does not have power... it is just for lights. It will be a 7 pin round..... there is a switched power lead there. There is also a reverse lead in that harness also.

So to recap....

Run your RCA cable from the camera jack on the stereo to the camera

Run a wire from your reverse lead on the stereo to the back up lights.

Run your power wire from your camera to a switched lead

Ground the camera.

Tape all connections

Secure ALL wires to frame

DONE!

I have the AVH-P4200DVD with the bypass relay in place. DVD works when vehicle is in motion. I just bought the AVIC-U220 and from what I am reading, if I hook up the Navi unit, I will lose my ability to play DVDs when moving. Has anyone found a solution to this yet? I do not care so much if I lose some features on the Navi system when going above 10mph. I contacted avhbypass.com and they said:

 

"Apparently there's an accelerometer inside the Navi unit that tells when the vehicle is moving above 10mph to shut off a certain functions of the unit. This is a mechanical item and cannot be bypassed via electrical circuit. A solution hasn't been found for the navi add on yet."

 

I just would like to know if anyone has connected the U220 AND can watch DVDs too...without having to detach the unit from its cradle prior to starting the vehicle up.

 

Thanks!

I have the 3200DVD and the U220 Nav. I have tried the relay bypass and it works WITHOUT the Nav unit. As soon as you plug in the nav, it will not bypass. I simply installed a switch and flip it off then back on and it will be bypassed. The relay was removed, the parking brake wire was hooked to one side of the switch, ground to the other.
