16:9 screen blank, no LEDS

[rb0135]

Hi All,

Just doing a retrofit (MKIII and 16:9 screen) and thought i would plug everything in to test.

I get a red light on the NAV Unit, the radio comes on and I can use the steering wheel controls for the radio.

BUT, I get nothing on the screen, not even a light, and the controls on the screen certainly dont do anything.

I dont have a MAP CD in the the unit.. Do you have to have a map CD before the screen is turned on?

The guy I got the screen from had a photo of it working.

The cable is not a retrofit cable, but a replacement harness.. Do I need to jump pins on the TV/Vid module connectors to "turn on" the screen.

Can ideas? Please help.
