Went on holiday over the weekend. The sat nav was working ok but then suddenly lost track of itself and the display said I was driving in the sea. I tried a reset of the infotainment (holding down the power button for 10 seconds) but it didn't help. In the end I had to turn the whole car off and lock/unlock it for it to reset. The following day I was heading home and all was good until it suddenly froze. Then it just kept saying recalculating route and in the end after rebooting it (including pulling into to a layby to turn car off/on) I got really annoyed with it all and plugged my phone in and used Android Auto which worked perfectly for the remaining 2 hour drive. The display on the digital cockpit was still coming up with all sorts of random stuff including saying part of the motorway was a 5MPH limit. It never did get its bearings again.
It has done this a few times now. Is it a known issue ? I could do a map update but I don't think that would fix it as it couldn't even decide where it was.
Cheers.
