Went in for it's first service yesterday, a bit late but all went well except...... I was informed that my speedo was not working (OBD fault code I guess). To be honest I tend to use the HUD most of the time but I'm sure I would have noticed if it wasn't working. What could have happened is the right side of my wonderful dash went completely blank one day but I was still able to drive legally cos the HUD display was showing my speed. They very kindly did a software update to cure this problem. Alas my sat nav maps totally vanished but everything else was working i.e. directions etc. After quite a few restarts the maps reappeared with a map of the world and I could see I was in England! All's well now but the sat nav does not appear in the HUD as it used to. There is an "empty" slot where it used to be but nowhere can I find a way of getting it to appear again. Any ideas anyone? Or will it just appear by magic one day. If it means another visit to MB for another software update I'll leave it till next year.
