Android 7.0 Causes iDrive to constantly rebooot...

[gizard]

... My Xperia Z5c running Android 7 causes not only a 2013 5 Series with Pro Nav to constantly reboot but also a 2016 F80 m3 to constantly reboot the idrive system - which is rather annoying. I think it is the messaging side of the sync that is doing it - as on the M3 if I get into the phone settings on idrive and turn off the message part it appears to behave itself....

Any suggestions?
