I had car in for a repair and they took it on a 13 mile test run. I think they been messing about with the controls. The heated seats controls were on maximum, the info screen just above steering wheel was stuck on “!”, two bars on petrol gauge when I handed it in with four and sat nav no voice. It’s Sat night so not happy. I switched off the heated seats and eventually after fiddling with selector wheel left side of steering wheel I got info screen back to normal. When I went out in car message displayed saying I need petrol so filled up with just over 27 litres. For sat nav no voice, after watching a YouTube, I went into General Settings, System, System Volumes and Navigation Guidance the volume is very high so stumped on what can it be?. Still no voice. Any ideas?.
