If u got one with navigation from best buy or somewhere it should come with everything for the navigation to work correctly. As for the factory chimes and sounds you will have to buy a wiring harness for that. If u got a GM navigation system it would cost more and you would have to buy a antenna and wire it in the roof or dash or where ever it goes

I don't have navi ATM but there's a add on available for it I might get down the road.
 
best pic i got, you will need at least 2 extra parts, u need to buy a dash kit like 20 bucks and an adapter to have ur door chimes and everything work i think the part is gmos-01 another 30 bucks. all easy to install.

If you have the Monsoon sound system and you intend to keep the Monsoon amp then you will need the GMOS-04 adapter and it will run you anywhere from $80-$120 depending on where you purchase it.

when you swapped the radios you lost the calendar right? Are you still able to view your mileage? I have a 2004 grand pix gt and im looking to swap, i dont mind losing the calendar but i wanna make sure i can view the kilometres
 


Yea you'll lose the calendar feature...no buy deal 98% of aftermarket HU have a calendar anyways plus that's what a cellphones for. You will keep your kM/MPH.
