Look just click the Spoiler 'Show' button above the red 'warning' in my last post. Extract the zip file to find the "he_IL.kbd" file. Read the warning copy and if you want to proceed connect your navigator to the PC in Mass Storage Mode and look for the folder named 'keyboard'. Place the file in there. I cannot give you any warranty that it will work as it's meant for zumo 590 which the BMW Navigator V is based upon. If it bricks the device we should be able to help you fix it easily.
