E90 and E70 Same Nav Discs?

[jimf15e]

Does anybody know if the nav discs for the E90 (2006, pre-RTTI if it matters) and E70 are the same, ie. interchangeable? The part numbers differ only by the last digit. Not that I'd try to get away with buying only one nav disc update or anything... . Thanks!

At my knowledge, there are just two different navigation systems using DVD: The "High" (older) and the "Professional" (current). As it seem it is the Professional version on E90, it should be the same. Just check on your existing navigation DVD in your E90 to check if it is written "High" or "Professional".

All US models only have Professional sat nav. I, for one, would like the cheaper Business sat nav which just gives you arrows and no map. But it'd just confuse the hell outta Americans, who are used to having a sat nav with full color maps.
