Just bought a 05 gtp

Was wondering what I need to install a head unit and if I can use a 5 button dic in it

If it has Monsoon GMOS-04 nonMonsoon GMOS-01 would be the adapter. Dash kit, steering wheel module if you plan to keep those. You will lose the calendar feature on the DIC if you go with a aftermarket unit. Yes u can swap to a 5 button.. Search there's a write up somewhere about it. Oh and you'll need a radio antenna adapter.

I don't think it has the monsoon I don't see it labeled anywhere but I can just switch to a 5 button or do I need anything else besides the dash bezel

Does it have a speaker on the dash.. If so then yup it has the Monsoon system if no then nope it doesn't have it
