Hello, I am trying to do a software update to my radio on a 2015 cvo limited. It says the ignition switch must be in the accessory position. Does anyone know which position that is? The ignition know says locked or unlocked so should I turn it to the right or left? Also, when I put the usb thumb drive in it says do I want to update but only the no is highlighted not the yes. Does anyone have any thoughts on this? Thanks
