Hello everyone. I am kinda new to the board so dont shoot me if you already know this. I have a 06 Commander with the factory navigation. I was burning cds last night and by accident burnt a mp3/multimedia disc. Well come to find out that thing plays in the factory navigation. I then made another cd with 160 songs on it, from a normal cd-r disc. It plays all the songs. Not only that, you use the navigation toggle like a computer mouse. I played around more and put the songs in computer files, sure enough the files show up on the screen of the navigation. I used nero to burn the cds. If you have any questions just reply, this is very simple to do. you can now have over 900 songs at once with 6 cds! All the songs show up in a playlist and have the artist,title and even album title when you push info. I am gonna mess with it more and if i come up with anything else i will let you all know!!
