HELP!Go to Official Hyundai Motors Navigation Update Website
You don't give up anything by doing either the Quick update or the General update. The quick update only updates what changed, not every file, and you can't use the system during the update. The General one updates everything, regardless of whether it changed, and I believe you can use the system during that time, but it takes several hours.
I have tried this multiple times ( for a PC) and while the Navigator Update Setup copies to a USB or my PC, the InstallShield Wizard does not run. I really don't know where to go from here. Any clues would be much appreciated.
