I bought a Vantec Bluetooth Audio receiver. It receives audio from a Bluetooth transmitter (phone or tablet) and converts it to analog audio. I connected it to AUX 3 using the included 1/8" stereo cable.
It works but the audio quality is much inferior to a direct connection between the phone and the Jensen itself and if you power it via the included USB cable, it generates an annoying amount of background noise.
Thus far the best way to play MP3s is to load them onto the memory card in my phone and connect the phone directly to the Jensen with a 1/8" stereo cable. It isn't sexy, but it is functional.
I'd like to have it work wirelessly, so I can have my phone with me around the trailer. I may try another Bluetooth receiver, one that supports APTX.
Another thing that bugs me about the 970 is that you can't use the USB port for charging. As soon as you plug a USB device into it, even with a charging only USB cable, the radio switches to USB play mode. There is no way to use the radio, CD or Aux function when a charging device is plugged into the USB port.
