I have a Pioneer AVIC 700 head unit in my car. The AVIC is a 7" touch screen NAV system w/TV-in ports. I'm not always the driver, when I go places, and even if I am, being able to hear the game is better than missing it all together. The TP2, my original choice, has 800 x 480 resolution, which would be 1:1 pixel mapping with my head unit. Closest Outlet mall is 1.5 hours away...and the others are "out of state". SlingMobile + Slingbox = watching your cable/sat/DVR service on your mobile phone in HD, or preconfigured res.
