MK3 sat nav blank screen

2 posts in this topic

Ok, I'm cheating a bit as this is in my e38 not my e39.

 

Had no sound but did have a display. Removed amp from boot, had to remove nav unit, tv unit and cd changer first.

 

Soldered dry joints on amp, connected it and had sound!

 

Put everything back together but now no screen, looks like it is backlit.

 

Red light is on nav unit, taken out and reloaded cd, disconnected and reconnected battery, after about 5 mins, but still nothing.

Any ideas?
