This is for Lee20:
If your car is Model Year 2020, then 2020-Q1 is the correct download.
You can go to ‘My Vauxhall’ to confirm your Model Year.
After inserting the USB drive, ignore messages like ‘Media Error-No Files’ and wait for the slow read-speed of the car to sort itself out. You may take it out and try again, but wait longer than you want to.
Maps for Pre and Post model year 2020 are found here: -

Doing mine now, had the progress bar, about 2/3rds the way though then it’s gone off and the screen is blank? All functions work but no map is displayed?

There is a known issue with the 18.0 map update. Some 3008 and grandlands stop the installation the first time. Just redo it and it wil install fine.

I have had the same problem, the second installation went normal.

All sorted, tried again - no issues

Does anyone know if this latest update to the firmware works with a mid 2018 Grandland? I only ask because I haven’t managed to get the MyVauxhall app connecting to my car via bluetooth, despite trying everything.

My car is 68 plate and it works on my car.

Tried the firmware update, but says incompatible with my car, i think i have the newer wave 4 version, the sat-nav updated ok to the 18.0 version with no problems. Anyone know if there is a new firmware with the wave 4 yet.

The error message can because its not downloaded correctly. Also have you tried a few times in the car as sometimes it can come up with errors and then install.

Mine is a 2018.5 build, the firmware worked fine with mine, With the MyVauxhall app it would not connect to my car no matter what I did and Customer services were not able to help, just before Christmas a raised a case again using the Contact and assistance section of the app and mysterious a couple of days later it started working and has worked every time since.
