I wanted to know what parts I would need to install an Alpine Ina-w910 double din unit. I have a 2013 gsr with the factory basic radio. I would like to connect to work with the steering wheel controls. I would like to use all functions on the stereo (navi, Bluetooth, iPod/iPhone...)
I already bought the American international dash kit.

 

just the Metra streeting wheel adapter I believe.

 

You need a pac steering wheel adapter for the controls to work. I have one for sale in the marketplace. Open box item.
