Central RT6 (eMyWay) stuck on logo or black screen.

The RT6 multimedia system (Magneti Marelli) uses a internal Micro SD card (hidden inside the motherboard) to store the operating system and GPS maps.

• The Chronic Cause: Because this card is of low quality and is exposed to the excessive heat of the dashboard, it ends up becoming corrupted over time. When the control unit tries to read the boot files and fails, it enters a state of emergency. looping The Citroën logo remains infinity or it simply doesn’t turn on (black screen).
• Secondary Consequence: Since the audible signals (turn signals, reverse sensors, and alerts) are processed by the control unit, if it “dies,” the car becomes silent, which can even cause accidents during maneuvers.

How to Solve:

1. Micro SD card replacement: It is necessary to open the control unit, remove the original card and replace it with a good quality (Class 10) 8GB or 16GB card.
2. Recovery Software: Simply inserting a blank card isn’t enough. You need to write the operating system image (firmware) to the new card and then run an update CD or USB drive so that the car recognizes the radio again.

Location of Protection (Fuses): Before disassembling everything, check if it’s not just a power outage in the… BSI (Cabin):

• Correct Fuse: Generally the F8 (20A) or a fuse identified with a radio/musical note symbol. Removing and replacing the fuse may force a “reboot” which sometimes resolves minor freezes.
