Hi Deepblue,
My car has had a complete software suite update after I had MG app connectivity issues. The connectivity issues arose after some warranty work was carried out. Someone accidentally disconnected the 12v battery whilst the car was in it's 'Ready' state. That's like shutting down your Windows computer by pulling out the plug from the wall socket. It caused some software corruption. Myself, dealer & MG customer support tried all sorts to correct the problem but to no avail.
In the end the only solution was to upgrade the telematics software that runs the cars main computer from R25 to R27. Once this had been carried out the car was able to see upgrades for all 6 other computer modules in the car. The technician duly downloaded & installed these additional upgrades. After that all connectivity issues were cured. Everything works great now.
If your dealer tells you there are no other updates for your car when it's running R25 inform him he can upgrade you to R27 & loads of other updates will immediately become available. These should cure your issues. My car also wakes up & charges it's 12v battery when it's needed.
