Hello,
I am driving Cruze 2012 with navi. I have pretty much all extras on the car except Bluetooth pairing and phone control.
Can you tell me what do I need to do in order to have this function in my car? I accept only original solutions. After market solutions are not acceptable.
I will be looking to purchase all the necessary parts, but I would like to make a list so I can calculate the cost and to keep things in track.

I am thinking of:
steering wheel control
Bluetooth module
new radio unit maybe ?!
radio button panel
wires

what else can you think of?

also if you know a video on YouTube or a blog post of someone who installed the phone control system, I will be glad if you share it here, as I did not find anything online.

Thanks in advance!
