First of all - try to reset your navi - close all doors, opet trunklid (to have access to navi), wait till navi lid goes off, disconnect all cables from navi, wait 15-20 min, then connect all cables. Then take CORRECT navi SW (in correct Mode, write it on the lowest speed, make error check and surface check) and after resetting your navi try to update with this soft..... Hope and pray! ....

Hope it helps
