I was wondering if there is a way to toggle between all 3 different inputs (nav, aux1, and aux2) manually on Dom's navi converter. I know that you can install a switch to toggle between the nav and aux1, but that doesn't let you toggle between the 2 aux inputs. Any help will greatly be appreciated. Thanks.

 

Wire another switch and 12v to the blue/white combo, or get a 3-way rocker switch and set them all up together, that should do it.

 

Will this solution still enable the backup camera to come on automatically when the car goes in reverse?

 

No, that makes it a manual toggle. I suppose its 'possible' to make it so with an extra relay in front of this setup, but I'd be giving you bad advice if I said I knew how to do it.

Try an install shop if you want a setup that complicated.
