Hey all, looking to install an avic 8100 on my own and was curious about the Universal Steering Wheel Control. Do i need to buy one if my car already equiped with buttons on the steering wheel to activate the audio to make a call? I guess it comes down to the connection in the back of the 8100? I drive a 2012 Xterra.

Yes, you will need an adapter module. I suggest an idatalink Maestro SW: http://maestro.idatalink.com/product/product/product_id/101
