OK, I finally got the V29.1 to work in my M-5 that has an MK4 in it. Very cool. Thanks for all of the support from those of you here that are smarter than I (probably most of you!).

Now my challenge is to get my Range Rover updated. It has an MK3 in it and shows SW version 3-1/32, which interestingly enough does not show up on any of the update charts that I have seen. It also has a male Brittish voice, so perhaps this was a "grey" unit from the UK?

In any event, anyone know how to get the MK3 to update? I have tried V22.1 and 29.1, and all I get is "Incorrect CD" on the screen. Could this be because it is a Rover (even though it has a BMW Nav unit)?

Any help would be greatly appreciated. Thanks!
