Stop/start disconnects audio on restart
 

I have 2016 V40 that has had problems with audio cut out since day 1. Recently I began to realise that when the car stops using stop/start feature it loses audio when restarting. It also loses Bluetooth and sometimes it loses GPS too.

If I switch auto start/stop off it doesn't seem to happen.

It also seems to happen randomly ... Feels like a loose connection but dealer can't find it. They said it was map update huh!??
Anyone else had it? How to fix it?
