Its just a standard DIN fitting. The only adapter required is for the wiring if you don't want to chop the factory harness.


edit:

I forgot to mention that OEM head unit does not have speaker level outputs, just line level that connects to the amp in the footwell. This means there isn't a direct speaker connection on the head unit connections in the console. You can use the line outs from you new unit and retain the factory amp, or you will need to run new speaker level cables to the doors or down to the amp location and pick the speaker wires up there.
