Hello from Brazil!
I'm trying to recover the correct firmware for my **Yatour YT-M06** digital audio interface, which is connected to a **Pioneer DEH-P5950IB** head unit.
The head unit detects the device as a “CD Changer” (MULTI CD / CD-ROM), but:
- USB, SD and AUX do not work
- No files are read
- Only CD text is visible
After 10 years of trying and researching, I discovered that the YT-M06 must have a specific firmware installed, known as **“Pioneer 1”**.
🧠 The internal microcontroller is a **Fujitsu MB89F202**, but mine had the label scratched off — I confirmed it via online reverse engineering forums.
📷 I’m attaching:
- A picture of the radio screen showing MULTI CD
- A photo of the Yatour internal PCB, where the MCU is visible
---
Does anyone here:
- Have a working YT-M06 in a Pioneer radio?
- Have access to the **Pioneer 1 firmware (.bin)**?
- Know how to dump the firmware from a functional unit?
Any help would be greatly appreciated! 🙏
If needed, I’m open to collaborating on firmware dumping or testing.
Thanks in advance,
**Eduardo from Brazil 🇧🇷**
AI: Have you already tried updating or reflashing the YT-M06 firmware? If so, could you share which methods or tools you used, and what the results were?
NO!
AI: Do you have any info about the current firmware version, serial number, batch, or PCB revision of your YT-M06? This might help others check for compatibility with their own units.
NO!
