Upgrade Medianav 9.1.3 To 1.0.13.1 -

In the ecosystem of automotive infotainment, few systems have inspired as much devoted, if begrudging, community attention as the Medianav—the telematics unit found in a range of post-2012 Renault, Dacia, and Lada vehicles. While it was a leap forward from basic radio units, its aging architecture, slow interface, and susceptibility to bugs have made firmware updates a rite of passage for owners. Among the most discussed upgrade paths is the jump from version 9.1.3 to version 1.0.13.1. At first glance, this seems counterintuitive: why does a higher number (9) downgrade to a lower one (1)? The answer reveals the fragmented history of Renault’s software, the perils of open-source licensing, and the intimate bond between a driver and their dashboard.

Understanding the Version Paradox

To understand the upgrade from 9.1.3 to 1.0.13.1, one must first decode the nomenclature. Version 9.1.3 belongs to the original firmware tree based on a proprietary, often sluggish, operating system. These versions, culminating in the 9.x series, are known for frequent Bluetooth dropouts, a laggy GPS, and a peculiar inability to remember USB playback position. In contrast, version 1.0.13.1 is the final, most stable release of the Medianav Evolution firmware, based on a newer kernel. It is not a "downgrade" but a migration to a different software branch—like replacing the engine of a car rather than tuning the old one. The "1.0" represents a fresh start, offering reduced boot times, improved touchscreen calibration, and a more responsive interface.

The Why: What 1.0.13.1 Offers

Owners of the older 9.1.3 are rarely driven by curiosity alone; they are driven by frustration. The newer firmware promises several tangible benefits. First, USB stability: the 1.0.x branch handles larger drives and more folders without crashing. Second, Bluetooth audio quality improves markedly, with fewer skips and proper track metadata display. Third, and most critically for daily drivers, the reverse camera activation speed increases—a safety feature that shaves seconds off a maneuver. Early adopters have also reported that the GPS fix becomes faster, and the system no longer "forgets" radio presets after a cold start.

The How: A Ritual of USB Sticks and Patience

Upgrading a Medianav is not an OTA (over-the-air) process. It is a deliberate, slightly nerve-wracking manual operation. The user must locate a USB 2.0 drive (formatted to FAT32, no larger than 16GB) and download a specific, often community-sourced archive of 1.0.13.1, as official distribution from Renault has long ceased. The procedure is simple in theory but tense in practice: with the engine running (to avoid voltage drop), the USB drive is inserted. The system reboots automatically, displaying a cryptic progress bar. For two to four minutes, the screen might flash, the audio might crackle, and the dashboard looks like a computer in cardiac arrest. Upon success, the system restarts into the cleaner interface of 1.0.13.1. Upon failure—often due to a corrupted file or a cheap USB stick—the unit may enter a boot loop, requiring dealer intervention or an emergency recovery disk.

The Risks and Realities

This upgrade is not without peril. First, it voids any remaining warranty on the infotainment system. Second, not all Medianav units are hardware-identical; early 9.1.3 units may lack the necessary NAND memory to run 1.0.13.1 smoothly, leading to slower performance than before. Third, the process can "brick" the unit if interrupted. Finally, there is a legal gray area: version 1.0.13.1 contains embedded maps and navigation licenses that may not recognize the original VIN, potentially locking the GPS functionality. Owners must therefore back up their original device partition before attempting the upgrade—a step that requires Linux command-line knowledge.

The Community as a Service Center

Because Renault abandoned long-term software updates for these units around 2016, the upgrade pathway from 9.1.3 to 1.0.13.1 survives only through enthusiast forums (e.g., Forum-Renault, DaciaSanderoStepway). These communities act as unpaid QA testers, sharing checksums, hardware compatibility lists, and troubleshooting guides. The upgrade is thus as much a social process as a technical one. It transforms the solitary act of driving into a shared project—a digital handshake between strangers who agree that a five-second faster startup time is worth an evening of staring at a flashing USB drive.

Conclusion

Upgrading Medianav from 9.1.3 to 1.0.13.1 is a journey from the old to the slightly less old—not a revolution, but a refinement. It is a testament to the persistence of car owners who refuse to accept that their vehicle’s technology should age faster than its engine. While a modern smartphone does more in a second than the Medianav does in a minute, the act of upgrading it teaches us something valuable: that obsolescence is not absolute. With the right file, a FAT32 drive, and a willingness to risk a black screen, a 2014 Dacia can feel like a new car again. That is not just a firmware update. That is automotive alchemy.

It is important to note that you cannot software-upgrade a MediaNav Evolution 9.1.3 to version 1.0.13.1 because they run on fundamentally different hardware and operating systems.

Version 9.1.3: Based on Windows CE (LG LAN5200 WR2 hardware).

Version 1.0.13.1: Based on Linux (LG LAN5800WR0 hardware), often referred to as "MediaNav Evolution v2".

To transition from 9.1.3 to 1.0.13.1, you must perform a physical hardware swap by replacing your current head unit with a newer Evolution v2 unit. Hardware Upgrade Process

If you acquire a MediaNav Evolution v2 unit (version 1.0.x.x), follow these steps for the replacement:

Verify Compatibility: Most MediaNav units from 2012 to 2018 share the same physical shape, mounting points, and rear connectors. Remove Original Unit: Carefully pull off the plastic dashboard surround.

Unscrew the four Torx screws holding the 9.1.3 unit in place.

Disconnect the wiring loom and antenna cables from the back. Install New Unit: Connect the existing wiring to the new v2 unit.

Secure the unit with the Torx screws and replace the dashboard trim. Configuration: Enter the Radio Code for the new unit to unlock it.

Access the MICOM menu if needed to enable specific features like a reverse camera or to toggle the "WAKE" setting if the unit does not start automatically with the car. Managing Your Current 9.1.3 System In the ecosystem of automotive infotainment, few systems

If you choose to stay with your current hardware, 9.1.3 is considered the final official stable version for that platform. You can still perform maintenance: Update MediaNav 9.1.3 to Android version 1.0.13.1?

It is important to clarify the terminology. While the version number "1.0.13.1" sounds numerically lower than "9.1.3," it represents a newer software architecture (Generation 2) that Dacia/Renault introduced around 2016.

This upgrade is not a simple map update; it is a system firmware migration. It replaces the underlying operating system of the navigation module, allowing it to run smoother, render maps faster, and support newer map databases (TomTom maps).

First, let’s decode the math. Medianav 9.x.x is the old Linux-based interface. It is clunky, limited, and looks like a Wii menu from 2008. Medianav 1.x.x is the newer Android-based interface. It is smoother, supports modern codecs, and actually understands what "touch response" means.

Think of it this way: Windows 98 (9.1.3) vs. Android Auto-lite (1.0.13.1).

Owners who have successfully upgraded from 9.1.3 to 1.0.13.1 report a night-and-day difference. Here are the key improvements:

Do not skip this section. An improper upgrade can brick your head unit (requiring a dealer visit with a €300+ fee).

Upgrading from Medianav 9.1.3 to 1.0.13.1 is highly recommended for 95% of users. The improvements in stability, speed, and smartphone compatibility are undeniable. It transforms a frustrating, laggy system into a reliable daily driver.

Do not upgrade if:

Pro Tip: Before starting, take a photo of your current system information screen (version 9.1.3). If anything goes wrong, a dealer can use that photo to re-flash your unit, though they may charge a fee.
