Just tried to upgrade the nav maps on my 2011 E350 Sedan 4-matic. I bought the official navteq upgrade for the 2010/2011 E-class cars. When I insert the disc, I get an error message that the maps are 'incompatible' with the current system. I do know that this car is a late build for 2011 and I've heard there were some command changes for late build cars.

Would this matter? I'm unsure what to do.....2011 car and 2011 map upgrade. What else?
