If you have the factory fitted nav then this is an integrated system and you will need to get the clarion repaired. If you give me a call I can advise you how to arrange to have the unit repaired 0161 428 2020

Mercedes commans sat nav version 4.1 for E220, is saying off road, and when at home is showing on map that I am somewhere in the National Park Peak District. I have been told to remove fuse for sat nav should be no 28 but in boot of car near sat nav cassette fuses in box only go upto 20. Am I looking in the right place?
