You use the brackets off the stock radio to mount the aftermarket one. The only other thing you need is a universal toyota pocket which is about $15 and a standard toyota harness which is another $15. I'd look for a place that sells metra, best kits + harnesses, or american international. Stay away from Scoshe... there kits are like puzzles to put together and their harnesses tend to be multiple harnesses all compiled into one kit which is a pain in the ass..
