You know what siteguru I have got iPhone yes but before the update it was very hit and miss in getting it to work but I have not tried it since the up dates but will do. Maybe it now works.So you've really got 1100R10 in your (wife's) MG4 SE SR? That's old ... and I'd expect that to show the Android Auto pre-production message. (If you use Apple Carplay then you may not see it).
Yeh the wifes 4 is on 1100R10 4 SESR model.
