Hi Dodi,

I read on the BMW Navigation System FAQ that BMW have stopped development for the MKIII at version 3-1/63, which was introduced in V22.

I've downloaded V22 and can confirm that my software (as reported on the screen) is already 3-1/63.

So if I download V23, and install, I will *still* be on software 3-1/63.

But if I had a MKIV unit, V22 will give me software 4-1/20 and V23 will give me software 4-1/30

That's my understanding, based on the FAQ, which can be found here:

Can you have a read of it and confirm? (see page 4 of 8)

Also, I read on another thread that V23 is not suitable for upgrading MKIII units, because it causes problems, but it's not 100% confirmed.

Cheers and thanks for your help in pointing me towards V22, which has updated my MKIII to the latest software version.
