The stupid thing is the hyundai app works perfectly for navigation. You can search and find places just as you would inside, say Google Maps, and then send your choice to the car. I ended up doing that (before lockdown) when going to Swindon, and as I say it worked a dream. Well almost.
As I approached the destination the stupid satnav took me down some backroads. But that's because the satnav, as yet, hasn't got the latest updates and so knew nothing about the relatively newly built shopping complex and the new access roads.
