I have a few questions on what I will need if I install a new head unit. The one I am looking at (no model in particular) is a LCD touchscreen with all the gadgets - Bluetooth, DVD, Nav, iPod, steering wheel control...I don't believe there is sat radio though.

If I want to maintain most of what my car has stock (09SS, Bluetooth, Onstar, Steering Wheel Controls, Door Chimes), what do I need? I know you need the PAC brand adaptor for the door chimes. Do I NEED the steering wheel control if the head unit has an input? It looks like a single wire, but do I still need the PAC module for the controls? To maintain Bluetooth, do I need any accessories or is that controlled completely through the new head unit? I ask because I saw another PAC brand accessory for bluetooth, and mention that their Onstar compatible harness "does not work with bluetooth" so I am confused.

Lastly, does the stock SS head unit put out the full wattage, or is there and extra amplifier somewhere in the car that powers the subwoofer, or if I get the new head unit will I lose volume because the new unit is only 200W?

 

i don't know much about how the blue tooth works in the newer models but here is a good list for everything you will need. a couple people have a list is their how-to, but its not complete.


THESE FOR SURE: (part numbers may be a little off, someone can confirm)

Pioneer AVIC-Z110BT head unit ($900)

GMOS-lan-04 wiring harness (lets you keep onstar,etc) ($160)

Pac-SWI-PS (Steering wheel control adapter) ($40)

Metra 95-2001 (double din dash kit) ($10)





Optional:

Pioneer CD-IU50V (ipod control) ($45)

PIONEER GEX-P20HD (hd radio tuner) ($95)

Pioneer GEX-P920XM (xm radio ) ($95)



thats all i can think of for now

 

Ok, thanks. That's what I figured I'd need. I wasn't 100% sure if you needed the steering wheel control, and the statement about "not compatible with bluetooth" on that part number for the wiring harness worried me because for me, I will not give up my bluetooth.

I still wonder if the sub is powered by an amp seperate from the head unit too.

 

cructhfield sell a similar harness for 60$ fyi
