Found this website for this cool remote(Navigator). Has a touchpad, power button, video playback buttons, volume control, and a search button. Its made for a Home Theater PC setup. But thought it would work very well w a car PC. Works w PC and Mac and connects wirelessly. The remote is $50. Dont know how well it could or would integrate w the front ends that are available but its something real cool I found i thought I would share with the community. Check it out.
