But the mmcs use the HERE maps. The HERE app on iPhone shows new roads built in 2017 (also on offline maps) but the updated 2023-a I put in the mmcs yesterday does not. I would like to think the map would be the same after all since they are produeced by the same company using the same data.

Okay I see the difference in the processes. But still think it's weird roads are lacking in the 2023 update that was built in 2017. It was of course not on my 16 map. But on the 2024 here phone Navi they exist, and also if I put it in offline and download Norway. I can't imagine they put those roads in first in 2024 when they were there since 2017. But I do se that on my car the speed limits are updated and that is limits that changed 2-3 years ago. Is the here phone map not the same as the map for car Navi? Even though it's same provider

That is what I think is weird. Because I downloaded the app on my phone HERE wego that for sure has updated version and it is showing the roads that is missing from my unit. Even though it said 2023-a is the update supposed to be done in seconds? I read if you buy the original SD from HERE it will take 80 minutes and you use the user slot and leave the original card in the map slot. It's no way I am paying 1800kr for official map update.

I don’t know if i succeeded or not. It now says I am under versions 2023-a. I used to have the original map from 2016. what makes me wonder is that it still misses roads that are built after 2016 but some years before 2023. i follow this guide and winhex failed with the sys file saying i needed to perform it trough windows PE. I tried again with the img iso file from your other guide but still used winhex. it gave no errors and succeeded. put it in the car map slot it asked if i wanted to update and i pushed yes. i think it updated in like 10 seconds. i tried also update navi application and that also took just a few seconds and rebooted once and never factory reset itself. The pnly thing I see updated are the speed limits on the roads mostly. I live in Tromsø Norway
