Class adapter - was recognized with super iOS - iPhone or iPad - both no problem - reading and encoding worked great. Unfortunately, my BMW (E91 / BJ 08) two controllers were not recognized. Thus, I can not turn off no seat belt reminders. Possibly even write to the support of BMWhat App. The most important functions but I have to make. That would not have gone so fast and cheap at friendly without stress. Conclusion: do not want to miss .. reading and encoding has never been so easy.
