Ok, I thought I would be a guinea pig with the '2017 Head Unit Software' update.
I burned the iso to disc went out to the car and put the disc in. It flashed up that the disc was unreadable for a split second and then took me to this screen.

I wasn't really 100% whether my current version (X3E12008) or the version on the disc (X3E52007) was newer? Mine had 2008 at the end and the disc 2007 so that had me suspicious. However, I updated it and saw several screens like this.

It seemed to put the disc's software on with no problems - took about 5 minutes.
Updated screen shows that it definitely updated (or backdated

).

Anybody know what software version is newer? What the newest version is etc?
Not tried the Sat Nav set? Anyone had any luck? My maps are showing as 10-11 Map No.1
