So today i installed the tvandnav2go in my 2004 g35x. I had no problems, took apart dash and plugged in the nav2go unit, got power from the 12v ciggarette lighter and grounded on a bolt by the left panel of passanger seat.

The unit powered on and my Gps and screen is working great, but when i use the switch to toggle between modes ( i had a dvd player to test if i get picture) the screen wouldnt change. Is the switch bad? or maybe i did something wrong. Please help if anyone had a simialar problem before.
THank you

 

You would probably get more responses if you post this in the Audio/Video section. I don't have a clue what to suggest unfortunately.

 

thanks, im kinda new to the whole online scene. Appreciate the help tho
