NAND Flash Dump or Recovery Image for Nissan Murano 2011 AV Control Unit

[leecat]

Hello everyone,
I’m looking for a NAND flash dump or recovery image for the AV Control Unit in my 2011 Nissan Murano Z51 (Right-Hand Drive).

• AV Control Unit: Calsonic Kansei 27760-1AE1A
  
• CD/Radio Module: Clarion PN-3059H-A
  
• Features:
  
  • DVD-based Navigation (DVD/Bluetooth unit in glovebox)
    
  • BOSE audio system
    
  • Rear + side cameras
    
  • No USB ports

The unit is showing the following faults:

• Hangs or resets during animated NISSAN logo
  
• After second boot, display is stuck on STATUS with AUDIO OFF
  
• Screen does not respond to button inputs
  
• No audio output
  
• Climate system works, but display doesn't update

I suspect a corrupted NAND or software boot failure.
💾 I’m specifically looking for:

• Full NAND dump (*.bin or *.img)
  
• Reflashing procedure or JTAG/UART access advice
  
• Known working backup from the same hardware revision

If someone has a working unit they can read from or can help clone it, I’d be very grateful.
Thanks in advance!
