Chris,
thanks for replying.
Yes, all the controls work fine. I can see the screen change in shade but nothing displayed.
When i first tried to start, all i heard was clicking. Next i turned on the radio to check if it worked...which it did. After a minute, my screen goes blank.
I replaced the battery and car starts right up, radio plays no problem but no display. Yes, i tightened down the battery once. I did a search but no available solution.:sad1:
Ooh - the clicking is bad. When you get that point, power to the car's electronics is interrupted as all the juice is going to the starter. That could mimic rapid battery connect/disconnect, which is very bad for the Nav.
When you say "After a minute, my screen goes blank" - are you saying this happened once after you hooked up the new battery (you had the display for a minute, and then it went away and never came back)? If this is the case, things are most likely bad.
The backlight is turning on, which is causing the change in screen contrast. I have a failed Nav unit that has the opposite problem - the LCD works, but no backlight.
I would try dmz's suggestion, if you have the Nav firmware CD. I have a feeling it's probably in the display, but it can't hurt to try reflashing the Nav firmware, especially since you had the clicking when trying to start.
cheers,
Chris
