Just got through hooking up the pcIII and im having problems getting the map of my bike to come up when the bike is running. Im pretty computer literate so I followed the directions step for step. I can pick which map I want but nothing comes up when im trying to pull up the map of my bike when its running. Can anyone please guide me in the right direction!! Could it be my USB cord??? I installed and then uninstalled twice...green light shows on the box. What else am I doing wrong here?
