it uses a button on the NAV screen to switch audio sources. the video sources are cut in via relay to switch to rear view, or a switch as well... in essence, no difference.

thanks. that helps.

You may want to also look at the Dietz interface. It offers a similar solution to the others mentioned here, however does allow the external video to be selected (or not selected as the case may be, regardless of if the source video is available .ie DVD playing) with a button on the NAV Screen. The clock button to be exact. No new menu item appears. Its just done by pushing the clock button momentarily.

You can find out more info here

I personally dont have one of these, but am currently looking into it .... just thought I would mention it !

Cheers, Adrian

Anything can be used for a switch though - its simply the fact of grounding a trigger wire. How you would want an external switch to be utilized would be up to you.

We've had a couple of recommendations from using the ebrake, to using the cigarette lighter. I think we're both on the same path to which we want to keep the installation as factory-like as possible.

BTW - out website will be fully functional by Jan 1st - it's a work in progress.

Looks good Adrian thanks for the info. I'll call today to find out about price/availability and let you know. I did get an email back from Parag so now I have three to choose from! :)
