MK3 satnav screen very dim
 

The screen on my mk3 satnav has gradually become very dim over the last few months, to the point where it's difficult to see in the daylight.


When I disconnect the satnav cd unit the default "blocky" screen is normal brightness, but when I reconnect the unit the screen is again very dim. So I'm assuming the problem is with the satnav cd computer itself, or the connections.


As an aside it has stopped ejecting the disc when the eject button is pressed - this may be unrelated. Everything else works, and the red light goes out after a few minutes as normal.



Any thoughts gratefully appreciated.
