Thank you!!!!!
1. I used 4 different computers, with windows11 and 7, installed all the necessary files. The DLM never seen the storage spaces on these computers
2. Tried 8 different USB, same results
3. Ended up borrowed a neighbor 25 year old Dell laptop with Windows7. As soon as I installed the DLM, it recognize the USB strorage space!.
4. Plugged into the car, car saw the new map version and offered update. As soon as I input PIN, car stated "map cant be update"!?. Tried multiple times, as soon as I plugged in, the car stated "map cant be update", no option to change PIN or any setting.
5. Trigital review my files, suggest different USB. So I bought another new USB 64gb, formatted to FAT32, ... as soon as I plugged in, it started updating without asking for PIN or asking if I want to update!.
6. 30 mins into update, despite the ignition was on, the COMAND went into sleep!. Its scared the hell out of me. Turned the COMAND back on, went back into navigation, and it continued to update!!.
Quite a journey with this map updating..... Again, thanks Trigital for all the knowledge, supports, help and materials. Without him, I would have abandoned this from the very beginning
1st, download the Download_Manager_COMAND_Hard-disc_navigation
2nd, put in a usb in pc and formatted as screen shows.
3rd, Patiently and wait for download to be finished. (It depends on your internet it may take 30-60mins)
4th, Put your usb in front car usb console.
5th, either have car running or have a battery maintainer it will take 30-mins to 60mins.
6th put in a map pin and wait for installation to be finished.
🚗 Step 1: Acquire the Magical Map Files
Find your type of Navigation system by inserting your VIN number Here and take a note.
Download and install the software that will allow you to get the latest map files from here
Start the program and plug in the USB stick, making sure it’s formatted right (your USB is formatted to FAT32. Yes, FAT32. Not exFAT. Not NTFS. FAT32. Your car is picky).
Select your map and download it…
🔌 Step 2: Plug It In, Baby
Insert the USB into your car’s media port.
Your Navigation system should wake up and say, “Ooh, new maps!”
If it doesn’t, try turning the car off and on again. Works for everything, right?
🔐 Step 3: Enter the Sacred PIN
You’ll need a license key.
If you don’t have one, just ask nicely here, and someone will help you out. No, I can’t guess it. No, 1234 won’t work.
⏳ Step 4: Wait Like a Zen Master
The update takes about 40–60 minutes, so bring snacks.
Make sure your car stays on or in accessory mode. If it powers down mid-update, your maps might think you live in Narnia.
🎉 Step 5: Celebrate

There are rumors on several forums that Volvo use the same NTG type and they has 2025 Map versions. Some claims that they managed to use the Volvo files to update the NTG4.5/7 to 2025.
It will be a great contribution here if you find more details about that, as I never had the chance to verify this information.
