They are probably read the forum and had the fix from here then ?.
I don't know any dealers that have time to read forums such as this one!
My Trophy Connect LR came from Richmond Motors in Portsmouth with this 'fault'.
I was told it should have had a software update!
Why wasn't this done automatically during the PDI?
Anyway that sat nav now works, that is until you have a DC charge, when it 'forgets' the route! No amount of re-entering the route will get it to continue!
It wasn't a one off either, and happened again after the next DC charge. Two different DC chargers by the way, before anybody suggests it was a particular brand'! BP Pulse and Instavolt if anybody is interested,
It is perfectly OK after an AC charge.
Another 'funny' my car has is the volume of the radio being adjusted by the throttle!!
I was listening to a newish DAB station in the Portsmouth area and every time I released the throttle the radio went quiet! Touching the brake also reduced the volume!
I do have to say it was OK on any of the BBC stations. Most weird.
The only thing I can think of is that some DAB stations have dynamic controls and maybe the MG has a way of tapping into this!
