Unzip on your desktop and on a CLEAN FLASH DRIVE.... copy ONLY the ISO file...In my USB there are maps after unzipping the iso file The Harley does not update, what am I doing wrong? The HD site says to put in the USB after the ACC switch. Here first USB and then ACC. What did you guys do?
Did the boom box 6,5 download. Are you guys talking about the 4.3 boombox update? or also about the 6.5?
Then plug in the flash drive and turn bike to ACC
These directions work for either 4.3 or 6.5... just make sure you downloaded the right file for your system
