Which head unit would you pick and why? Im torn between the 2. I would like good sq and great video quality. I will be hooking this up in my tahoe to the factory speakers, for now, and a jl audio 250/1 and a single 10w3 D4. I know the clarion http://www.sonicelectronix.com/item_6710.html supports video playback from the ipod. Im not sure about the panasonic http://www.sonicelectronix.com/item_6751.html Any help or opinions on these HUs would be great. Thanks
