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

Hi MottiF,

Yes, the IDA dissassembler is expensive but worth it. It used to be $15,000 if I remember. This is a GrandMaster tool; not a cheap freeware.
Even better if you can get also the ARM decompiler. Then you would be able to regenerate the source code in C and with a bit of work recreate a new manager.exe.

Manager.exe is a pretty much standard Windows program so even when looking at the assembly code you can figure out the Windows messages and how they are handled. Even easier with the decompiler of course. I would suggest first look at the Winmain function and then from there figure out how the config.ini file is handled and then how the rrui file is interpreted and loaded. Easy stuff. The difficult part is how to recognize the MCU functions because these are hard-coded (thank you again RR for this bad design). All in all it's not a big program so with some work and a lot of patience it's doable. Another thing that could help you is to grab one of the debug versions of manager.exe floating around. That would help a lot at first to understand manager.exe architecture.

My Android 6.0 has no problem either; never tried 7.x yet. Be careful on where you stored the contacts (and how many).
If I remember RR uses only the SIM contacts (not the Phone contacts or Google contacts or what not...). There might be also a limit on the numbers of contacts but mine is OK at around 40. I never need to share contacts with the unit; I let the unit download the contacts automatically; it doesn't do it all the times so it works fine for me. Not sure what is the meaning of bt_pb_num; would need to experiment. Maybe the folks at China-RNS know.

Fun stuff!

 

Hi Arturo,

1) First, read post #1 of this thread ; it contains information and detailed steps about upgrading OS, MCU and Shell.
Not specific to your unit though.

2) There is a readme.txt file. The rest is not hard to figure out. Be aware that the UIEditor was made for earlier UI versions. So it is not always usable especially which newer shell versions. Some shell functions are reported to disappear after editing...
There is also a RRUITool you can use; it can do more but it is very painful to use...

3) Yes; see post #1. Very slow on these units because the browsers are outdated; most websites won't even run properly.

You might also want to check with our German friends at china-rns.com; they support a wide range of Roadrover units, they have many downloads available for MCU, Shells, and much more...

Enjoy.

 

Reverse is used for backup camera; connect to your car reverse wire.
The other ones are (probably) for your steering wheel buttons (if you have any).
You should have a label on the unit or a user manual that would explain all that...

 

Hi Renkli,

Roadrover units do support the Turkish language; unfortunately they translated only a few strings; the rest is in English.
There is a way to edit 100% of those strings yourself but you will have to work a little bit...

See post #350 on this thread:

If you do try this, I recommend you make a backup of your unit just in this case.

 

Hi Airwin and welcome.

Dropbox has changed the way the hyperlinks work.
They are now supposedly safer but unfortunately that means all the previous posted links are broken...
(Not sure I can fix all those previous links at once... it didn't work last time I tried).

But for now you can get the latest version here: Dropbox - RRUIToolv12M.zip

Enjoy

 

Hello Sercan,

here's a new link for the RRUIEditor.
Be aware that this tool is compatible only with older skins (<2.78).
You might be able to edit the newer skins but some of the UI elements might lose their functions IDs.
You can however fix them with the RRUITool if you have enough patience; but people say it is not easy.

As for the Opel skins, sorry; this is only a Prius site.
You might have more luck with our German friends at http://www.china-rns.com.
They have a large collection of skins and software for Roadrover.

 

Hi Kavah,

you will need to post both skins here: the one that works and the one that doesn't.
Then we will can compare the 2 skins and find why one is not working.
Sometimes the editor will corrupt the the skin; the icon id might be right but not the function id.

 

Hi Kavah,

If you are sure that the ID functions are ok then maybe your MCU firmware does not support those functions.

So the first thing to do is to verify with your vendor if you have the latest MCU, UI and skins.

Please confirm.

 

Try also our German friends at www china-rns com ; they are very supportive of European cars.
They also have a huge section for downloading skins, MCU, etc; may be they have the right version for your car.

Good luck.
