AVIC-MRZ99 Custom Firmware / Testmode
Hi,
sorry for posting in the wrong Subforum, but I didn't find a M-Series Subforum.
I bought a Pioneer Carrozzeria AVIC-MRZ99 on eBay.
It's a japanese Unit from an imported Car.
The Problem is, you can't change the language to english... you can't change it generally :/
Does anyone know if I can install another firmware to this device?
Maybe this device was sold in EU or USA with another Name.

Hi @Mwassaru
Just use sources: https://github.com/Shtirlitz/RZ09
Cut 0x200 header of PRG-file - you'll get the .NB0 firmware.
Extract initDB.dat from .NB0 file, use my tools to make the translation.
Replace translated initDB.dat in the .NB0 and use makever.c to create updated FW files.
Here is step-by-step manual (2 posts): http://4pda.ru/forum/index.php?showtopic=847671&st=20#entry90149444
It's in Russian but I think it's easy to translate to English.
Good
