At the risk of sounding redundant, you should look for another installer b/c you do not need a switch nor should you have to give up the bypass to accomplish what you're trying to do. I have the same setup as you, installed everything myself and have no issues with the camera. Here's what you need to do:

Camera Power: Connect this to switched power, this way the camera is always on when the car is on; now when you switch your nav view to "rear" you will get the camera feed.

Avic Reverse Input: Connect this to the car's reverse signal wire. All this does is tell the Avic that you're in reverse and switches the input to the rear cam.....hence no manual switch needed.

Video Cable: this should be obvious.

None of these connections have anything to do with the bypass, so I'm not sure why your installer thinks you have to give up the bypass.....again, you're best bet is to get another installer.

Hope this helps.

Thanks for the info guys, looks like I’ll be ripping my dash apart again…….

As for complaining to the lot owners, I don’t know how far it will get me since I can’t prove which one (at least) of the 15 attendants is messing with my radio. I doubt the clown would fess up when asked. Plus, I only know the radio has been messed with when the AV source is set to anything other than off or if XM is tuned to a station that I don’t listen to. For all I know, some attendants may be smart enough to set everything back to the way it was to avoid any trouble; or they may learn to do so after a complaint is filed. This is why I would rather put in a kill switch so they can’t mess with it…..

I’ve been lurking here for a bit and this being my first post, I’d like to say thank you to everyone who has shared their wealth of information.

So here’s my issue, I have the x920 w/bypass and everything is working as it should. The problem I have is that I park my car in a paid garage with valet service and unfortunately the Avic gets too much attention from the parking attendants. When I enter the garage, I always turn the AV source off but have noticed from time to time (when picking up the car after work) that the source has been changed to XM or the CD was playing. I let it go the first couple of times, but when I picked up my car yesterday, the source was changed to FM & tuned to station playing music in a different language and the part that pissed me off the most was that my EQ settings were changed as well. I didn’t get an avic for other people to play with.

Since the unit powers on with the car, I am thinking about adding a kill switch of sorts for the avic, this way the clowns in the parking garage can’t kill time by playing with my avic. My initial thought is to wire a hidden toggle switch in between the switched power connection of the car’s harness and the avic’s harness. I’m no expert but I think this should work. Any upside or downside to doing this…..or a better way to accomplish the same goal?

Thanks in advance for your help.
