I installled a Z2 in my carrera, Im trying to change the wallpaper with other pics and am unsuccessful... Im using a Mac so probably not using the right software, can anyone help me out with what software to use, and also if anyone has any original pics for porsche to share.

Sorry, I can't help you re: burning the images from a mac, but there were some really nice Porsche wallpapers in the threads on the custom backgrounds. I used them in my Boxster, and even the dealer is impressed with how nice they look.

You should be able to use Toast and change the settings for the cd. Just sellect iso 9660 and 8+3 file name if possible and make sure the pictures don't have any weird characters in them (in the name not the image itself).
