At random times throughout the year, my audio will switch a few times, or rapidly, between the radio, aux, usb if my phone is plugged in.

it *seems* like it happens more when it’s cold, but it’s done it in all weather types. I can usually recreate it if I touch the aux port.

do you think this is a short issue, or a wire problem, or something else? It’s annoying, to say the least, but not an emergency.

It seems like a loose connection to me. I would check all wiring connections going into and out of the head unit.
