Coded my X1 to auto fold/unfold with holding lock/unlock button using BMWhat app. It was as easy as ticking the boxes and I did it during my lunch break at work
. No hassle of going through internet to find all those installation files, daten files etc. Just that you have to wait for the Bluetooth adapter to come through then you are done. App can be installed through Android/Apple App Store. Cost me AUD$64. Just my concern at this moment is is something were to mess up how can I restore factory settings..
Regarding auto seat positioning it seems to work only if both keys are used. If other key is used and the seat is repositioned, using the main key will set it back to the position setup for the main key and vice versa.
