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:

Hello

 

I did the same on my MRZ09 and it looks way better. I have a similar issue with maps for Europe. Anyone has them available?

Hi

 

Do you possible have a full backup of the MRZ-66? I have tried all the others but I must either be doing something wrong or the files dont work.

 

Please assist! :)

Hi, deas anybody have the dumpromx.exe ? As I have an avic rz501 and aperantly without this software I can't make the translation to English.

Also if somebody has the files already prepared for this model I would highly appreciate the effort as chances are I'm going to brick this one :)
