Very. The wiring harness behind the dash are different from an '05 to '06. Different enough to be a pain in the ass and a few have attempted to install in '05s and given up. If you are serious in attempting. Do a search and read up on it.
This is a steal of a deal. The OEM setups that I've seen in the past went for almost double that.
