Hi, was trying to upgrade my avic 80 dvd with cndv 50MT v1.2 disk and now my nav wont' work. I called pioneer and their support hotline says that i need to use 50MTP. On the web site it shows a picture of 50MT when you clikc on 50 MTP. Anyone know if there is a difference between then two?

Thanks

I did the same thing with the 40MT disc. The addition of the "P" indicates that the software is built for a remote control interface.
