sat nav display
 

Hi All

I'm looking for a bit of help with my 2004 E270CDI. I've had a sat nav retro fitted and it works fine including DVD on the move BUT there is a slight glitch in that the buttons don't illuminate at night - although the comand screen automatically goes to night mode - and the directional arrows shown on the comand screen dont show in the centre of the speedo. Any ideas

Thanks very much
