Yeah 2004 but the errors I had spanned the entire 645 time before the 650 came online If you start to notice any issues with iDrive...get to the dealer and have the stack changed out.

Now I'm big on buying and dumping cars, but I don't know that you would want to run out and pay top dollar for a used 645 to dump it less then a year later
