Ahh, I never really thought about it from a DRM standpoint. That makes much more sense though why they would do that.
Im gonna go TOTALLY off topic now. Is there any way to access the full potential of the AVIC's screen. Like if someone wanted to put an XBOX360 under their seat and have a vga/dvi cable run to the AVIC? I know that 800x480 would be a supported resolution on the 360 if you used the VGA route.
Whats the deal with the EXT1 / EXT2 inputs on the menu, I googled to try and find out how to use them because I have dreamed up all kinds of schemes for external video sources. Another one I want to do is put one of those cheap DTV tuners under my seat and be able to get ATSC Digital Television on my AVIC while driving so I can watch basketball games.
Short of cracking open the unit and making your own wireing harness directly into the screen no.
As for the EXT1 and EXT2:
EXT2 is the minijack on the front, Its actually an AV input for another video or external device.
EXT1 is the RCA's on the back currently occupied by the iPod. If you disable the iPod in setup you will notice that EXT1 now is un greyed.
