Map Update
Hi there, I have got an X3 D20, 2011. Bought 20/21 maps from BMW but when I insert the code that they gave to me it says it's not valid. At the BMW local dealer that said that the main unit might be changed and need reprogramming (but it does work properly). Asked precious owner and he told me that he hasn't changed the main unit.
Any suggestions?
Many thanks.
