Hi I have the AVIC X1. Firstly it wasn't reading DVDs but sorted that now. I had a grey screen saying insert appropriate disc on the navi screen. I spoke to pioneer support they said it would need a full factory reset. Which I know how to do (I think) or to get the CNDV 110MT. I got the disc attempted loading it today and now I have a black screen that says insert appropriate disc and it will not let me go on to any other view. It's just stuck on this screen! I tried doing a full factory reset but it won't let me use the joy stick. Any ideas??? Thank you
