Long time lurker here. I got my iphone 5 when they were first released as was really worried after reading here as well as on Pioneer's website. I've been checking this thread daily to see if there was any good news which there appeared to be..

I just got my lightening to 30 pin adapter and tested my iPhone in my truck on the Z120 and I am pleased to report that it worked just fine. I was able to navigate my playlists
