Have had the same since purchasing the car in July ‘21 and, despite trying new cables and cleaning both the car’s USB and my phone’s charging port, I have still not found a solution. It is most annoying (and dangerous) when you’re on a call or using the CarPlay maps for directions and it cuts out, leaving you desperately scrambling around in a moving car. Had it happen so many times but I’m still struggling to “live with it”. Inbuilt satnav is horrific and no other functions on screen work (HVAC etc) when you’re in an active call. Can’t believe these type of significant errors made it through testing/ quality checking and into production AND STILL have no fix.
