DZO hi. Tell me please what is the reason, after the translation, and the subsequent compilation of PF090JPJPN.LNG through the command ./recode translated.txt PF090JPJPN.LNG, the terminal produces a segmentation error (a memory dump is made)

 

There's no error checking so it'll do this if it can't open the input file. 

[Muhammad Kashan Sultan]

Hi DZO,

 

Can you please advise if there is any instruction how to change boot splash screen on mrz77?

[Muhammad Kashan Sultan]

Thank you very much DZO and IInur for your help i successfully changed Japanese to English language on AVIC-MRZ07  with your help.  i appreciate you guided me on every step . Thanks again.

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:

Hey Dzo, i followed your installer and extracted it onto USB however when i plug in usb it says copying with red screen then it says done with green screen. However it doesn't seem to work.

 

I tried to turn off the car when doing installation and after completing restart.

 

This was for the AVIC MRZ90.

 

First i was trying to convert to english and once that's done hopefully i can load NZ maps on it

any help would be appreciated it.

Mrz90 is a bit older than mrz99 so it probably has different strings. Can you get into testmode and copy all of /USER to an sd card then post /USER/PRG1/APL/MENU/Image.img and everything in /USER/PRG1/APL/LANGDATA/ here. I'll see what I can do.

 

I'm in NZ too, I don't think putting NZ maps on these devices will be easy or worthwhile because the english versions never had NZ maps and Google maps is far bettter anyway.

Hi DZO,

 

Sorry to bother you again, but could you please advise if there is any instruction how to change boot splash screen on mrz77?

Hi DZO,

 

Sorry to bother you again, but could you please advise if there is any instruction how to change boot splash screen on mrz77?

 

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.............|

00000010  01 00 00 00 00 00 00 00  4e 41 30 39 30 4f 50 4e  |........NA090OPN|

00000020  ff ff ff ff ff ff ff ff  ff ff ff ff ff ff ff ff  |................|

 

with the other bytes 0xff

 

call it NA090OPN.DAT

 

compile the makever.c program from my github and run it with NA090OPN.DAT to generate NA090OPN.VER.

 

On a usb stick or sd card create a directory called AVICMRZ90 with a directory OPN090 inside it.

 

copy NA090OPN.VER to AVICMRZ90 as PF090OPN.VER and OPN.VER (I can't remember which is correct so just put both in there)

copy NA090OPN.DAT to the OPN090 directory and rename it as PF090OPN.DAT

 

start testmode and select "forced firmware update" in japanese, I think it's the third entry but check first using google translate.

select "opening image", i think it's the last entry but again, check.

 

select usb or sd card and a new version number should appear, if not, check your directory structure and file names.

hit menu (or it could be another key) and it will write the splash screen.

 

I have done this and it works but as you can see it's not a simple process, it took me a long time to figure out the directory structure and

when it finally worked I had the DAT and VER files in lots of places with different names so the above may not be 100% correct but with some trial and error you should be able to get it to work. There is no way to go back to the standard image.

 

I'm happy with the splash screen I have now so I'm not going to change it or spend time making this process easier.

I'm definitely not going to take requests to convert splash screen images into dat and ver files!!
