Edit: Alpine says........
Steering Wheel Remote Ready
This receiver is compatible with the steering wheel remote controls available in many vehicles. You can take out your factory radio, put in the Alpine, and still have the convenience of operating your sound system from the steering wheel. Ask your authorized retailer for available interfaces.
Let me know if you need one.
I'll have to get back with you on that. The Alpine has a remote input jack that has two wires labeled remote input out and remote input in. On the same jack there is a hookup for the reverse lamps (for camera) and for a monitor control (rear DVD). I assume that these two leads for the remotes hook into the interface from PAC?
Sorry for all the questions, my first DIY radio install that is more than a factory swap.
