Ottonavi HU: How to customize (a bit) the UI

Hello zml,
so yeah it looks like an old gen Roadrover unit.
At least you can do a partial backup; that's good.

The MCU is not a file; it's a micro-controller+firmware inside the unit.
The fact that you are able to run the I9 skins without the radio working proves you would need to upgrade the MCU first.
I'm not sure if this is possible in this case; you will need to find out the radio type first.
There are instructions on this thread ( I9 GUI on old Roadrover D2280) in china-rns.com that explains how to check for that.
Read the whole thread first.
Even if you have the right radio type, you will need to check if there is an MCU version upgrade for your unit.
(I checked very quickly in their download list and couldn't find anything specifically for your unit but there might be some compatible units.)

The best thing thing to do is to ask the folks at china-rns.com (they are very knowledgeable; ask Strados) to see if there is a way to upgrade your MCU.
If yes, then you can follow the procedure to upgrade the MCU, then upgrade the UI shell to I9 and enjoy the new skins.

***Very important*** Do not upgrade your MCU unless you are 100% sure it fits your unit and that I9 skins will work on the unit!
(Otherwise you unit could be broken forever...)

Thank you for a good information
I have new one is support android auto as shown in below[/QUOTE]
Hello Amer,
This looks like a Roadrover model running Windows CE and I9 UI.
It does not support Android Auto.

Hello Chuckman,

there are many possible reasons of course.

The most probable one right now is your usb key got corrupted or is too slow somehow.
Try with a different one or an sdcard with THE SAME video files and see if it works.

If not, there a good chance your video filters in the I9/Filters folder (in flash memory) got corrupted.
Happened to me once.
Then in this case, I would simply copy over the original Filters folder into the I9 folder.
(Skin 2.78.10 available somewhere on post #1)
That might fix it.

If that doesn't fix it, then I would reinstall the whole Windows CE.
This would reset all your settings too but at least you should end up with a clean system.
This one happened to me twice!
(Also look at post #1)

As always, for any fix, follows instructions carefully! You don't want to brick your unit!

Those damn flash memories are not always reliable...
(although mines have been working fine since then...)

 

Sure. The wallpapers can be anywhere you want.
To upload a wallpaper:
Apps>Options>Skins then in the Wallpaper section hit Browse and select the file
or
Apps->Files>Photos>Open>Options->Set As wallpaper

For the startup logo: read this: Ottonavi HU: How to change your startup logo | PriusChat

Should all work for your unit too.

 

A little bit risky to stop right in the middle...

Answers:
1) stylus for installing things yes; while driving a big NO!
2) The unit I9 folder should be here: \StaticStore\I9
Filters folder is here: \StaticStore\I9\Filters
3) Impossible for me to know what you did; but it's very possible that the unit memory (flash memory) is corrupted
4) Nav system is simply a Windows app on an sd card; should have nothing to do with your problem.

Radio volume not working is weird; So may be we need to reinstall Windows; read below...

A few words on how this stuff works.
This is a Windows machine and as such it supports a number of devices.
Some of them are:
\NAND FLASH: (Internal flash memory) this is where the gps parameters and other parameters-options are saved
\StaticStore: (another internal flash memory) this is where the I9 folder is (and Filters, etc)
\Storage Card: this is the SD card
\USB Disk: the usb drive
etc...
(The names might differ on your machine but they should look similar)

FIRST STEP
When I said * simply copy over the original Filters folder into the I9 folder*, this is what I meant:
1- copy the original Folders from skin 2.78 unto an sd card or usb drive.
2- insert Sd card or usb drive in unit and copy this Filters folder from USB or SD card to the \StaticStire\I9\Filters folder.
Check post#1 again to see how you can access the Windows desktop and copy files.
Try this first; at least to get you familiar with the process. And check how things work with the videos and radio. Should be quick to do.

SECOND STEP
If that doesn't work, chances are your unit memory is corrupted or doesn't have the right MCU or OS or UI versions.
If you are willing to lose all your settings, music, pictures, videos, etc. you installed previously, then you can try to reinstall Windows CE.
After you do, you will also have to reinstall one of the UI-skin. And then reinstall your music, videos, etc. Again post#1..

QUESTIONS (before we try anything...)
Did you try to install any other MCU or UI skin in your unit?
You said these were the original versions: are you sure?
Shell: 2.78.10
OS: EN-Prima-ARM-SLC-V1.50
MCU: D69TTRH7-BH-T1-V9.00

If not, then we will have to find out the original ones (or compatible) and reinstall them first.
If yes, then try FIRST STEP.
If that doesn't work, then unfortunately, to be sure, you will have to do SECOND STEP.

It's a scary step but it usually goes smooth; unless your unit is broken of course...

 

I'm glad it's working for you now!

About the video formats...
Most people use mp4 I think.
But I'm not sure if anybody ever tested the best formats for this unit yet.

If you do find anything, please let us know!

 

Hello Kiat,

It looks like you SD card is either corrupted or not formatted properly.
If you can read it on a PC then it's probably in the wrong format. Unless your HU is broken.

There are a few things you need to check...
1) Make sure your USB or SD cards are formatted using the FAT format; other formats are not always recognized.
2) Try with different USB or SD cards; sometimes they get corrupted or not recognized at all; happens to me often.
3) Make sure you copy a good Update.exe file on your SD card; there's one on post #1 in this thread.

Oh and it would be nice of you if you can zip the contents of your I9 folder and post it or send it to me.
You have a new UI version and it would be nice to see if we can test it so other users can use it.

Let us know,
Bulle

 

1. Leaving the sd card inside is OK of course; but not necessarily a proof that the sd card is still ok; it can get broken easily.
2. yes. Run update.exe again from the USB, go to Windows desktop and open MyDevice. You should see a list of disks and medias including USB's, memory disk and of course SD's. You SD card device should be there. If yes, you should be able to open it and see the files inside. If not, there's a problem with the sd device; in this case, try to reset the unit (reset hole if you have one). Or power off completely (disconnect the unit) and restart (that will be like a reboot). If device is not restored we might have to reinstall your specific version of Windows CE.
3. Not possible I think. The UI is just a data file read by the same program every time. Should not break anything.
4. Yes this file should be OK.
5. You should be able to attach the zip file here in your next post. Or you can send it to me as a private message if you want. (*Start conversation* under my Bulle icon.
