There is a install kit that will take care of the extra space problem on your "yota" quite well. It replaces the extra din space with a storage tray. It bolts right onto the same ISO bracket that the factory radio is removed from, where the new head unit will sit right on top of it. It makes for a very neat and professional looking install. I bought mine from beachaudio.com. They sell the kit very cheap. i think less than 20 bucks.
