Hello, I am new to the forum and was told this is a good place to inquire about navigation upgrades. I have a 95 E38 740il BMW with 16:9 wide screen and Land Rover MKIII running 3 - 1/31. I have attempted to upgrade the OS on the RR unit with V22.1 and V24.1 and everytime I insert the CD into the drive it gives me an error message saying that the CD inserted is incorrect.

I was wondering what version OS I can update to so I can remove the Land Rover Splash Screen and get a BMW roundel and if anyone can fill me in on the process. Any input would be greatly appreciated. Thanks in advance.

Also was wondering what was required to make a custom spalash screen...Would be cool to have a picture of my car when I open my door.
