Yes, holding that button will nearly always restore things but that is not easy or safe when driving on your own!
For something that costs upwards of £30,000 this shouldn't happen in my view.
Mine went in for a software/firmware update which improved things, but not completely, which I find frustrating.
If the phone is plugged in and Apple Carplay is working, this causes problems, not straight away, but after about an hours worth of driving!
West Sussex to Reddich it happened about 2/3rds of the way up the A34!
With issues like this how can a dealer get to the hub of the problem?
MG UK should call customers in and put a logging device into the OBD2 port so that when this happens they can call up the data at that point.
Other manufacturers do this why not SAIC I wonder?
One thing I forgot happened the other day in the cold weather was the emergency call disabled itself!
Luckily we only had cold weather here in West Sussex, no snow, but imagine if I had ruin off the road into a snow drift, I couldn't call for help! The prime use of the emergency call feature!!
Yes they are computers on wheels, but when did someone moan about the Windows blue screen of death (I'm an Apple user by the way) not since about 2015 maybe longer ago than that, computers have come on in reliability terms and now hardly ever crash! Having said that, I know what will happen, but I've got everything crossed!
I think you will find that the software inside the infotainment on the facelift models is HERE based and thus uses Linux?
