I finally received the obdeleven after 3 weeks of waiting and got stuck in. Never used one before so started with needle sweep to see how it works and after 3 clicks all done. So then I wanted to activate the lock/ unlock sounds and that's where I run into problems. I managed to access control unit 46 and before doing any coding i run the backup. The app kept crashing during the backup and after a few goes I started getting the message that the control unit is not responding. I tried many things like reinstalling the app, rebooting mmi etc. and still no luck. Then I installed the app on a different iphone and got the same message so that means the problem is not due to the phone. Tried to search on Internet for answers but didn't find any solution that worked. Has anyone seen this before and knows how to fix it?
