i may be selling one come tax time, i didnt want double din, but thinking custom carputer now.

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

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.

This. Putting a gto shifter in it whenever I get around to it.

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.
