Hello together, I drive a 2016 Spacetourer whose radio/navi needs an update. I did well after instructions and always get the error message that the update is not compatible with the hardware. Installed is current: system version 21.07.16.32_NAC-r0, map material 7.0.0-r0 to be installed: system version 21.08.90.52_NAC-r0, map material 28.0.0-r0 motor runs stick pure first error message with no software on the stick ignored (as in the guide schrr ieben) Then error message update not compatible with the hardware Who has solutions? Please no texts like leave it or take the phone as a navigator, that does not help us solve the problem. I am grateful for every hint in the right direction.
