but don't count on the DIN tool working...I was able to free one side of my head unit with the tool, but the other side wouldn't budge...so it was destroyed with a screwdriver until it came out. Your new HU will most likely come with a metal cage that will fit into the opening in the dash, you bend out a few pins to hold it in there, and slide the new HU in there. Most likely, you will have to trim some plastic off the opening in the dash. THere are actually little tabs in the corners. I used an exacto knive, because the dremel broke!!
