I use my phone for music sometimes using the bike's speakers by use of the blue tooth tunei. Works fine, but I have to use the phone for control. What I'm wondering is if I can do some sort of music control through the bike, by use of the Nav V, bluetoothed to phone and bluetoothed to the tunei, which is plugged into the usb port and input jack in the side pocket. Basically, what I want to do is play music off of my phone, either mp3 or amazon, and control it through the bike by way of gps, and fool the gps into thinking the tunei is a headset, so that the sound comes through the speakers on the bike. Does anyone think that's possible?
