Update - I got the Aux Input (69200907) installed on the bike. De-pinned and re-pinned into the CB connector. Took it to the dealership and had them update the radio to "interrupt tone and add device to mode list". The road tech 590 hasn't arrived yet but figured the Media player should work on my current Zumo 590. Tried it and no sound. Something hadn't set well with me when installing the Aux Input kit. In step 4 of the instruction sheet it says to "Connect the open end of the audio jack jumper cable to the mating Zumo harness connector marked "Audio IN". This isn't correct, it needs to be in the "Audio Out" connector on the Zumo harness.
After I corrected that I was able to play MP3 off the Zumo. My question is, I'm only getting music out of the left speakers, I'm hearing static out of the right. Is this correct? I plugged my phone directly into the Aux Input and got stereo from the speakers.
Thanks.
