First, my unit did not ship with the 4 screws needed to attach the small panel to the bottom of the main radio panel. How do I get replacements for them?
Next, what do I do with the two USB-A connectors after installing them on the back of the radio panel? How should they be routed?
Finally, do I need the external mic for making phone calls over BlueTooth and for talking to SYNC? If so, where should it be located/routed?
