i posted pics and explained what wires need to go to the stock radio for this installation in another thread in the car audio section of this forum a while ago
come back with any particular questions you may have
i prefer this install as to having the stock hu behind the dash since it gives me a permanent clock, stock look, and helps prevent theft, also my keyless entry goes out every once in a while and i need to reprogram my remote from the stock hu
