During my experience, I had encounter a lot of situations when the medianav was a freeze of blocked at some steps after some upgrades or some modifications that I’ve made. Unfortunately, I’m not the only one and I want to share the solutions tested with you.
As a BEST PRACTICE, you need to Install Bootloader before all (all version) or any modification on your Renault & Dacia medianav (mediaskin, GPS, map, repair, restoration … etc), you must make a security update for your medianav version, to be able to restore in case of installation error.

But if you are here I’m pretty sure that you don’t have a backup and need to try these solutions:
The best and fast solution is to take out the power:
- By taking out the + or – from the battery of the car [take care because after this you will need the 4 digit code of your medianav]
- By taking the proper fuse out and put in the back (depends on your car model)
- By taking the power muffle from behind of your medianav
This simple solution is helping on 80% of freezing. Now for the rest of 20 % that is not solved by hard reset we need to know how the medianav is structured and I already written an article before about that:
In some words you need to know that in medianav is existing 4 storage cards (3.6GB in total):
- STORAGE CARD [Usually is the SYSTEM data folder ~100mb system data
- STORAGE CARD2 [SHOULD BE EMPTY]
- STORAGE CARD3 [SHOULD BE EMPTY]
- STORAGE CARD4 [Usually is the NNG folder of the navigation] ~ from 1.9GB to 2.8GB
- +MD that is your USB stick
Before modify anything, or even a major modification in system I recommend always to make a Backup of your original system as it is, to be protected if you have troubles. Usually before I start any updating, I personally like to make a Backup of all system to protect myself in any event and so I found a very simple way with an application Total Commander that can be launched directly from the USB stick. The variants are below.
Backups have proven useful in many cases when MediaNav is blocked for various reasons and needs to be recovered. I recommend saving everything is possible from MediaNav. However, the most important folders are the Storage Card and Storage Card4 that must be saved.
With these references in mind, please be careful and be patient .. it will take some time..

you can get the backups files from:
Now you need a USB stick formatted as FAT32, and copy and paste the files in the main folder structure at is it:
Now if everything is inside you go to the car. Put the usb inside of the car start the medianav and wait for some ~5 minutes until WIN CE6 is appearing.
Next step is to going and check if the STORAGE CARD, 2, 3, 4 is existing.
- If the storages is not existing it means that the MEMORY CARD is blocked or freeze but you can restore with 2 methods:
1.Methode of MANAMA
This is the simplest way and only thing to do, is to have to open the app and push the buttons in these way: 1. Rebuild MBR/Partitions + 2. Format All
Even after that you will not see the STORAGE CARDS, you need to go in WIN CE 6 control pannel at Storage manager and check if PARTSXX is existing as bellow:
If is without * it means that are not formated as fat32 and are not mounted so the operation it will be: 1. Format as FAT32, 2. MOUNT, for all of 4 storage cards.
Now if the result are like bellow it means that the formating and mount phase is ended and need to check in my device if is appearing.
2.Methode of bypassing 2 R1021 si R1022, but is more complicated because need electronique skills and hardware skills and dismount. The most efficient is from GND and R1022 because it is more easy to managed.
- If the STORAGE CARD exists, you need to copy and replace first the booter_standalone.bin + NK.bin [for both MN1 + MN2] .
Now restart the medianav from my tool or by hard reset and check if the problem is solved.
If the problem is not solved you need to go and replace all the STORAGE CARD + STORAGE CARD4 from the USB with the total commander or by WIN CE 6 copy and paste function as bellow:
Once you finish the process of copying for both storages you need to restart it and the problem is solved.
The restart possibility is by hard reset of pushing a lot the power but usually is not saving what are you doing, then the most efficient it is by using the files that I provided upper: USB files for restoring the MEDIA NAV STORAGE CARD & STORAGE CARD4 +reboot WIN CE6 + TASK MANAGER → AFTER BEER DONATION 🍻 9.99€| PASSWORD: 926313
I hope that this tutorial is saving alot of time and save your medianav because in my case it was doing succesfully and takes alot of hours in order to get the winning method.
