iPhone5 plugin without function

Hello together, after I finally got my Ligthning Adapter for my iPhone 5 yesterday, I was full of anticipation that I can now finally use the connected plugin (via Y-cable) from my Mini. Unfortunately this only works partially. The apps “Driving Excitement” etc. work… but the PlugIn can not start so I have no access to the playlist with Coverflow etc. I always get the error message “No plugin capable device” and the “Self-diagnosis tool” doesn’t bring me any further Do you have the same problem? And has anyone already found a solution?? Thank you very much for your help
