Hi, what I would do if I were you is to download the newest maps for iGO 8,3, then backup, then update your device using the newest maps and hybrid 4.01 firmware. Just go through the hybrid 4.01 topic and you will know exactly how to do everything. http://avic411.com/index.php?/topic/33431-hybrid-4001-cnsd-300fm-guide-updated/page-1
