Hi Guys

Anybody come across this before?...just bought a 2002 X5 3.0i with the wide screen sat nav which all works perfectly ... except i cant see it at night...the function to switch between night and day works but its not illuminated at all so at night it looks like the monitor is switched off!! Has a bulb blown or is there a setting i can change? I have had BMWs with sat nav before and they all lit up fine at night!!

Thanks for yur help!........
