Comand map does not match location

[MEGANSBOB]

Hi
I have a W209 CLK and fitted a NT2.0 Comand. everything works except the map does not match were I am. I have put a new 2014/15 DVD in, the system tracks is just the maps wrong.

Any realistic suggestions on how to correct this please?

Change the GPS antenna. Or did you check from COMAND the number of satellites it can detect? Does it show "-" or "0"?
