Satnav and android car play gremlins

Evening, having had my brand new 21 plate VRS Estate from Skoda Colchester just over a week, i absolutely love it...generally....but i have two annoying gremlins.

1. When I set up android carplay it works really well apart from every now and again, randomly, the emergency SOS speaker makes a noise and, it knocks out the SOS function and a yellow service light comes up on the dash! I have for the moment deactivated android carplay!

2. The satnav is bloody useless. It keeps getting simple routes wrong and sends me miles away  -it seems to have a seizure and the go haywire and constantly says 'updating'. It's doubly irritating that the android carplay has an issue because the google maps and 'ok google' function work so much better than the voice control. Every posytcode also seems to be 'offroad' according to the system!

But, I LOVE THE CAR!

Any suggestions on the above?

Thanks
