Long time since I did anything with them and don't know about the 106R if it is different. I think you have to save the files individually and not put them into a folder on the CD? If still a no go, then suggest that you contact Alpine Technical Support, they will help you.

Hey, just wondering if you could help me out, I have an alpine 106r headunit and was wanting to put my own custom backgrounds on to it. I got some files from pride-rock in .apn format. When i put them on a cd-r disc, then put the disc into my alpine head unit, i just get "disc error" What am i doing wrong?
