I was doing an autotune yesterday while going for a ride on my 2015 RG. I had my iphone in bluetooth mode and the songs where skipping and I figured that music and autotune were using too much bandwidth so I plugged it into the USB port in the glovebox. When I tried to flash the new map it said it could not connect, I tried restarting the app, restarting the phone, and since I washed the bike Saturday I thought maybe the connection got wet. I took it off and made sure it was dry and reinstalled. Nothing....On complete accident I unplugged the phone from the usb port then tried to flash it and it worked perfectly.'
Long story short. Only flash using bluetooth
