Subject: USB ports on the R-23 ?
Are the USB ports on the R-23 outputs or can they be used to input, say, music to the radio. I'm aware that music form a phone can be streamed via Bluetooth to the radio, but also wonder if the USB ports are simply for charging devices or can be used to input data to the radio, or for that matter, to the Garmin Plotter ?
