AVIC-MRZ99 Custom Firmware / Testmode

Recommended Posts

I've translated the Japanese language strings for the MRZ99 to English. 

I figured out the format of the LNG file, dumped the Japanese, translated all the strings using google translate, then rebuilt the file.

Some of the English is not perfect but it makes the system much more usable. 

 

I've tested it with APP firmware version 3.070200 (installed with platform version 3.000600), other versions may not work.

If the old language file is 93627 bytes long then this will almost certainly work.

 

To install this, unzip the attachment mrz99english.zip and put the PF090JPJPN.LNG file on an sd card. (130905 bytes, md5sum is cb3f9cb76330704cc171e2b0acb9f6ad)

Get into testmode by holding the NAVI button (left button with Japanese writing on it) and pressing right..left..right..left..right..left and then release NAVI.

 

Go to the last entry on the first page (File Maintenance in Japanese) and press MENU (right button with Japanese writing on it) 

This opens the file manager which is in English and fairly obvious.

 

Make a backup of /USER as described elsewhere on avic411.com

 

Look in /USER to see if there is a file named  PRG.FLG

if there is, then the system uses /USER/PRG1, otherwise it uses /USER/PRG0

 

You can check the file versions by looking at  /USER/PRGx/PF090APL.HTM (where x is 0 or 1 depending on PRG.FLG)

 

go to  /USER/PRGx/APL/LANGDATA/

 

delete  PF090JPJPN.LNG

go to /SD, copy the new PF090JPJPN.LNG and paste it into LANGDATA where the old one was.

 

Switch off the power and when it restarts, it should be in English....

 

This worked for me but obviously is not 100% safe, be very careful in the file manager.

 

Update: There's now an installer that also changes the background and most of the important images with japanese text.

 

Find it here:

Go to the folder you want to backup. Select the files, and confirm that the + sign appears at the left of the files. Now select copy. go to sd card and select paste. put the card in your computer to confirm if the files are backed up.

I have selected english and I tried the other languages just in case it would work but it didnt

rename the downloaded PF090JPJPN.LNG AND PF110JPJPN.LNG files to PF090JPENG.LNG AND PF110JPENG.LNG. For safety backup these two files from prg0 and prg1 folders. Put the renamed files to prg0 and prg1 folders and see the magic!

Infect you not need to change the language from the navi menu. you only need to download the  PF090JPJPN.LNG AND PF110JPJPN.LNG files and put them to prg0 and prg1 folders.
