Hi,
I still have a MkIII and currently on V18.2 (SW3-1/41)
I would like to upgrade to the latest version that is v27 for the mkIII.

I downloaded the upgrade but havend burned it on CD-R just yet. From what I read on this forum, for some it work's and for others it crashes there system...
offcourse I don't want to crash my satnav, so I asked my dealer if he could upgrade it with official BMW discs.
He says it will take 45 min to install and cost about 50 Euro's.

What would be the best option here?
