Just wondering if you can get a personalised setting to link to a key? I've got my own settings but once I've been out the car and then put the key back in it reverts to guest settings so I have to change it every time.

So you don't get the "welcome driver 1" on the maxidot display. Do you have 2 keys

I changed the driver 1 to my name, but when I put the key next time I go for a drive it reverts to guest. I have 3 keys.

Just had a look at the electronic handbook, this may be of use.
