Download RNS 315 V.4 Map Update - SD Card

Download RNS 315 v.4 Map Update - SD Card

If you have a Volkswagen car with the RNS 315 navigation system, you might want to update your maps to the latest version. The RNS 315 is a touchscreen navigation system that features voice control, traffic information, and media playback. The latest map update for the RNS 315 is the v.4 version, which covers most of Europe and includes speed camera alerts, points of interest, and road network changes.

Download File:

To download the RNS 315 v.4 map update, you will need a compatible SD card with at least 16 GB of storage space. You can buy a genuine VW SD card with the map update preloaded from [SatNaviShop], or you can use a generic SD card and follow the steps below to make it work with your RNS 315.

Step 1: Download the map update files

The first step is to download the map update files from a reliable source. You can find the link to the EUR_W_V12 (2020-2021) map update files on [YouTube], where a user named Zulu Timeline has uploaded a video tutorial on how to update your RNS 315 maps. The video description contains the link to the files, which are hosted on Google Drive. You will need to download both the navpsf_update folder and the CID.txt file.

Step 2: Format the SD card and copy the files

The next step is to format your SD card to FAT32 file system and copy the navpsf_update folder to the root directory of the SD card. You can use any SD card reader or adapter to connect your SD card to your computer and use a disk management tool to format it. Make sure you back up any important data on your SD card before formatting it, as this will erase everything on it.

Step 3: Change the CID of the SD card

The third step is to change the CID (Card Identification) of your SD card to match the one in the CID.txt file. The CID is a unique identifier that is assigned to each SD card by the manufacturer and cannot be changed by normal means. However, there is a tool that can help you modify the CID of your SD card using a Linux command. The tool is called vw_mmc-tools and you can find it on [GitHub], where a user named TudorGruian has uploaded it along with instructions on how to use it.

To use vw_mmc-tools, you will need a Linux-compatible system and a compatible SD card reader or adapter. You will also need to install some dependencies, such as libudev-dev and libblkid-dev, which you can do using your package manager. Then, you will need to clone or download the vw_mmc-tools repository from GitHub and make it executable using the chmod command. After that, you can run the mmc command with the prog_cid option and specify your SD card device name (e.g., /dev/mmcblk0) and the CID from the CID.txt file (e.g., 5d53424c32424d31013917ca53010400). This will change the CID of your SD card to match the one in the file.

Step 4: Lock the SD card by password

The final step is to lock your SD card by password using the same mmc command with the lock_sd option. This will prevent any further changes to your SD card and make it recognizable by your RNS 315 as a map update card. You will need to specify your SD card device name (e.g., /dev/mmcblk0) and a password of your choice (e.g., C99A20843ED7D90B6801E49F2BC80277). Note that this password cannot be recovered by normal means, so make sure you remember it or write it down somewhere safe.

Step 5: Insert the SD card into your RNS 315 and update your maps

Now that you have prepared your SD card with the map update files, you can insert it into your RNS 315 and follow the on-screen instructions to update your maps. The update process may take up to an hour, depending on your system and region. Do not turn off your car or remove your SD card during the update, as this may damage your system or corrupt your maps. Once the update is complete, you can enjoy your new maps with the latest features and information.
