Thanks Daniel.

The head unit I've been looking at is the JVC KD-BT1 which has the same features but even includes built in Bluetooth for both phones and audio devices.

When I try to purchase it from Crutchfield I get the message that the deck needs to be wired directly to the speakers. Then I visited a local audio shop and they said they had issues getting a wiring harness for the Crossfire.

That is a nice looking head unit.
