Enable rear camera display while driving?

[moazam]

Hi all, I have the 2010 Prius with Navigation. When I put the car in reverse, the camera is enabled and I see what is behind me on the navigation screen. Is there any way to enable the camera to display on-screen while I'm just driving the car normally (i.e., on the highway, etc.).

My friends Mercedes has this feature so I'm sure it's not a legal issue.

I'd love to know a hack for this.

Yeah, my Lexus could do it using the NAV hack (which also overrides the in motion blackout). Unfortunately, Toyota/Lexus has disabled this hidden menu/easter egg in mid-2007 and later model years.

Looks cool when going freeway speed with the rear camera enabled.

What but grounding the reverse pin in the back of the nav unit?

Not sure what you mean, but I'd like to have the rear view camera turned on 'on-demand', not permanently on screen without use of Nav/Radio.

Hi, My Sienna has a AVIC-N1 head unit that supports what they call 'Towing View'. It is useful when you want to monitor something you are towing. It splits the screen so you can see the navigation map and the rear camera view. Not sure how useful it would be on a prius. At least having the option would be nice.

Behind the Nav unit is a wire labeled as "reverse." I'm guessing that this sends the signal that tells the NAV unit you are backing up. I haven't checked the wiring diagrams, but I would assume that it might just switch to ground when you are backing up. If that is the case, then you just need a simple switch to activate reverse mode. I hadn't really given it much thought since I wasn't planning on doing this mod, but I'll check the wiring diagrams when I get a chance.

Please let us know!
I'd really love to have this mod work.

A quick san f he wiring diagram tells me that the wire marked revers that feed into connector L42 behind the NAV (the pink wire in pin 5) runs to the integratino relay. It seems as though that relay may conenct the reverse wire to ground when activated. The relay is controlled by the power management ecu.

So it looks like my theory is probably right. A quick check with a multimeter can confirm.

This also assumes that that reverse signal is all the NAV needs to go into reverse camera mode (I can't verify that without trying it).

If it is the case, the only thing you'd need is a switch wired up the right way.

Is anyone going to try it?
