I am bench testing it before I put it in the car. So, I hook it up to ground and the yellow and red to 12v, insert disc, loads successfully, tell it that it is not a demo unit by hitting ok, goes to the time setting (i can see a map in background) and when I try and adjust time I get nothing, only the back touch button works, most of the other buttons work but some are grayed out which is expected because I dont have those options hooked up, goes to radio, goes to av screen, nav screen, but certain buttons are grayed. like trying to change back ground image, I can move around on map (LA) Im in Texas, I have the GPS antenna hooked up but its in the house so no signal, is there a wire I missed for bench testing purposes? What is the proper start up procedure for the D3 anyway? link to ebay of unit I bought, got it for 423 (had a 15% off ebay coupon).
