[QUOTE=reg]1) It is running 3-1/30.
You definitely want to go to 3-1/63

Does not ask for The CD key. My understanding is that insert the Update CD first then the key.[/B]

Yes, the process is simple:
1. Insert >V23 and perform update (any version after V23 is fine, they all contain 3-1/63).
2. After update, nav asks for Key CD. Insert Key CD
3. When nav has finished reading Key CD (a few seconds) it will eject Key CD.
4. Insert your map CD and enjoy!

PS: after major update, your nav will be empty. Addresses etc will need to be re-stored. Your nav will probably go to default coding (7er series, limousine, new-gen radio, no VIN number, etc)

So you should check and then code your nav to your car, using my NavCoder or the BMW software.
