I want to share my experience with an AVIC X1R (with CNDV 50).
I downloaded the 65 files and burn it with NERO using a SONY DVD+R DL disc with a ASUS CT30 burner.
I thought that will not run but:
At the first time the AVIC recognize the disc and now I´working with this new version without problem.
Sorry for my english and hope that that can help some users...
