without the rest of it you lose the ability to use the ac and heater. the factory head unit is integrated into the air control system so you need stand alone hardware to replace it.
the only way around this is to buy the lower dash installation kit and have 2 head units in the dash.

To be honest I might just go with this. It's a lot less of a hastle, plus I don't have to worry about climate control not working. IDC if I lose out on the storage compartments, I barely use them anyway.
