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.
Hard to find some infos about it, all in japanese language :/
I tried sev
Here are instructions on how to change the mrz99 splash screen.
First get an 800x480 image to use. Save it in 16 bit rgb565 format, strip the header off so it is exactly 768000 bytes long.
add a 512 byte header that starts like this:
00000000 a5 5a 5a a5 00 b8 0b 00 bc ea cd 15 00 00 00 01 |.ZZ.............|
