Thread: GPS in Hawaii?

So, in planning for my carputer, I want to do navigation. However, almost all the products I have seen only do street maps for CONUS. I know you can get satellites in Hawaii, because my handheld GPS gets about 5 satellites on average.

However, I want more than just location, I want maps and navigation.

Anyone have any idea if there is a product that includes Hawaii maps (or if Hawaii street maps can be purchased and added on to any products?)

Thanks
Dave
