Community Verdict

The consensus on forums like VWNavi.com and r/RCD_330 (which also discusses RNS units) is that Josi Work 5238 is one of the most reliable custom firmwares for older RNS 510 units that cannot officially run anything beyond 4020/4120. Users report:

Rock-solid daily driving stability.
No abnormal battery drain (unlike some 5270 versions).
Full map compatibility up to the final 2020 V10 European maps.

However, if you have an LED unit (H60 or newer), the official 5238 or the 5239 firmware is preferable, as custom patches are unnecessary.

Important Warning

Proceed at your own risk. Flashing the wrong firmware or interrupting the process can permanently brick your RNS 510, requiring a costly repair via JTAG or eMMC programmer. Always verify your hardware version first (hold Setup → Version Info → look for “HW Version”).

For most users with HW H50 and below, Josi Work 5238 represents the final, most stable firmware upgrade available—a fitting last hurrah for the legendary RNS 510 platform.
