Well, dropped car off at 8:00 and had a call at 12:45 to say fault had been fixed, turned out to be a poor or loose contact behind glovebox. I now have a map display on my dash and I’m a happy chap. Very pleased that they didn’t have to dismantle more of the car. Love the way you can shrink the dials slightly to give you even more map, so much safer than having to look at the infotainment screen. Thanks to everyone for their input.
