I am from Canada, I updated my GV80 Prestige navigation software yesterday morning. I used my Apple computer and downloaded the new program directly to the USB stick. When you are about to load the program the Genesis app asks you, 1/ What vehicle, 2/ What country. It takes about 40+ minutes to load to the USB stick. You then take the stick to your GV80, 1/ start the vehicle, 2/ push "Setup" button, 3/ General, 4/ I then inserted the USB stick, 5/ scrolled down to "Update", and away it goes.. Don't shut off vehicle, to me it seems like it took an hour to complete.
Caution, when the update first starts, it seems like nothing is happening, be patient it seems like it took 20 minutes before anything changed on the nav screen. But then you could see the %%% progress, I think it took an hour in total, I am not positive but it took a long time.
A feature I didn't know existed appeared on the 3D screen, if you just let the vehicle idle while it is updating or just idling in park, after approximately 10-20 minutes a "Timer" pops up (where the tach is located) and a count down begins. I didn't pay close attention to the starting minutes, but I think around 30-35 minutes. The vehicle will shut itself off when timer gets to zero.
I started to worry the vehicle would shut off before app was fully installed. By touching the brake pedal cancels the timer, but it will start again after 10-20 minutes.
A feature I found by accident. But when app is finished everything goes back to normal..
Did I notice any updates or changes??, not really, maybe someone knows the changes, if so, please let us all know..
PATIENCE is important.
