I was told to use the CR-V instead.
So in this link:
https://here.navigation.com/home/en_GB/HondaEMEA/EURchose CR-V for the model and then use the year 2025. On the bottom you can enter your VIN number and see if you are eligible for updates. In my case it showed that I am eligible for

will try to do it later. Need a 32GB USB formatted in FAT32
just checked. The version in my car is
1.75.134.432
2024.06.26
so that is pretty old.
When you fill in the VIN and the date of your version it will give you a download button. You first need to download the "Here Map Downloader", link is also in that page. When you download the program, it will start when you push on the download button. In my case the map for Europe is downloading. I am using a 256GB micro SD inside a USB stick to save it. First needed to format that in FAT32. Currently it is downloading. I guess when finished I take it to the car and use the menu in the settings of the navigation to get the update from the USB.
Not easy

I might stick with Tomtom. I even think the HERE App is free. Pretty sure the maps in the apps are updated more frequently. Well, I have been using the Tomtom app for many years and it automatically checks if there are updates for the maps that you are using. If there are updates it will notify you and this is several times per year. I think for the Honda-HERE maps there are only updates once a year.
