dontpannic Posted March 29, 2017 Report Share Posted March 29, 2017 You'll need to make something custom if you want that. USB will have to be wired up to a separate power supply, and the aux will have to be wired either to the plug on the back of the radio, or to a 3.5mm jack plug to plug into a aux socket wired to the back of the radio.
