Question Mekede /Navifly 7862 CAN code.

[Daro101]

Hi.
Can any of you add modified CAN codes to the 7862 radio? I have a Peugeot 308 SW car. Unfortunately, it is not on the car list. I am currently using the setting for the Peugeot 408. But not all functions are working. The steering wheel rotation codes that are used for the moving guide lines for the rear view camera are missing.

depends who is the manufacturer of the decoder, however try XP, or OD or check all, Android Settings > Car settings > Factory settings (password: 126) > Canbus tab > Select the manufacturer of your canbus decoder and the car model, or select the closest match if you cannot find exact model, e.g. volvo xc90 not on list but xc60 available. I hope it make sense.

I'm working on an open source CAN bus box for these sort of situations. The idea is that it fits exactly into the connector for the existing standard CAN bus boxes all these units use (so it will work for PX5/PX6/intel/UIS7862 etc). I've had a similar problem with my Audi A3, where the button functions are incorrect and unchangeable. My car also has an OLED display on the gauge cluster which doesn't show anything useful without the stock head unit (my primary motivation for this project). I'll make a more detailed post about it here once it's working smoothly in my car. For now I'm still working out a few hardware and software kinks, especially since I also need it to control my external DAC and gauge display.

To configure it for your car you will need to know the CAN bus communication rate, as well as the packet ID and bits changed for the following functions:

• ACC on
• Park
• Reverse
• Headlight/interior illumination brightness

Optional:

• Steering wheel buttons (if you want SWC)
• Dashboard display (if you have one - mine operates as 1 line 20 characters in my preferred configuration)
• Interesting parameters to monitor (fuel consumption, temperature, instantaneous speed, etc)

I'd also suggest being familiar with modifying Arduino code to change the packet values as I won't modify it for anything other than my Audi A3 8P. The way this data is coded can vary quite a lot car to car - for example in mine the brightness is coded as an integer from 0-100. You'll also need a way to solder the parts.

JLCPCB is insanely cheap for ordering boards if you're a new customer, and the rest of the components cost ~$30. I may build and sell some of my extra boards if there's interest, but I won't be providing any software besides for my Audi A3 8P. I'll update within the month, as I don't anticipate needing to change anything this point besides software, but only have 1 day a week to dedicate time to this project so progress has been slow.

Salut.
Poate cineva dintre voi adăuga coduri CAN modificate la radio 7862? Am o mașină Peugeot 308 SW. Din păcate, nu este pe lista de mașini. În prezent folosesc setarea pentru Peugeot 408. Dar nu toate funcțiile funcționează. Codurile de rotație ale volanului utilizate pentru liniile de ghidare mobile ale camerei de vizualizare din spate lipsesc.

Hi try these:

8888

6789

7890

Hi @COASTER19 .

Thanks for posting about this, always good to hear about real development work.

I for one would be very interested to read more about your project, would you consider posting more information.

Also, there is another thread discussing similar work you may not be aware of, so have posted here.

CANBOX , CAN decoder reverse engineering

Hi All, I have a PX5 radio that was supplied with fittings for 2006 Toyota RAV4 , sadly it didnt come with a CANBOX and supplier was not able to provide one that matched, I managed to get my hands on a Canbox for VW unit and decided to reverse...

hi all, i am new here and thinking to buy navifly HU
I have one question, dose the unit support climate control for AC? can I control my AC from unit?
The other question, can i add 360 cameras system?

It depends on whether your car exposes CAN-bus to the head unit and whether the provided CAN-bus box supports it. Generally, the answer is no unless specifically mentioned in the listing text. Navifly support doesn't speak good English, so I wouldn't expect a correct answer from them.


@marchnz I posted an early demo of the project on Youtube and have attached the latest schematic to this post.

I'll start a thread in a few more weeks once I get the optical audio working, but the current board layout probably needs another revision before then. I had to use a rotary tool to cut part of the board so the connector could physically fit. CANBOX looks interesting, but also works very differently from what I'm doing. I'll look into it more once I have a fully functional stereo again, as I'm definitely interested in trying to get some of those functions running.

Fantasic work, really like the approach to steering wheel keys.

What is selected for CANBus type on the unit to enable the split between analog steering wheel, Illumination, ACC and vehicle specific CANBus signaling say from car doors, AC etc?

I am very interested in making one and having a go at modifying the software for Toyota specific vehicles, if you're comfortable with releasing and commenting the source? Understand if you're not though

Great video. Thanks again for contributing to real development. Your work deserves its own thread!

 

[COASTER19]

Illumination, ACC state, Park state, and Reverse are just +12v signals onto wires. Normally, everything else happens over the serial communication, but in my case I use KEY1/KEY2 with selectable resistors for SWC.

Vehicle specific stuff such as reverse radar sensors, climate control, and door status would require reverse engineering the head unit's 2 wire serial protocol. Luckily it does appear at first glance that the protocol is the primary focus of the CANBOX project.

If there's a way to select an app to open over that serial connection it would be really convenient, but I don't think that's an option discovered yet. It would allow the mode carousel to be controlled entirely from the microcontroller which would be great. I loved how HAL9k's ROM on my PX6 allowed me to customize this, but my PX6 ran incredibly slow for some reason (20+ seconds to open maps). The 7862 is far nicer hardware despite the unpolished software, so the preferable option to me. Optical audio output is also great compared to the noise in both the PX6 and 7862 amps.

Ok. Couldn't find problem like mine. After starting car my dashboard HUD is in Chinese. Can't find anything like original radio settings to change it. Any ideas?

Use phone and Google translate to get to language menu?

Will use opcom to do that as navifly 7867 doesn't have setting for that inbuilt. Lots of cd400 radio settings are gone. Thanks.

I dont know what that has to do with using translate on your phone to find the language menu on your head unit, but if that spins your wheels.

 

[KDPD]

That means I can't change settings from head unit as that setting doesn't exist. It's not head unit language I'm talking about, it's dashboard display.

So using Google translate is impossible, hence I mentioned that opcom is needed.

 

[mastrv]

With the Google translate app on a phone, you can use your camera to point to the text and translate it.

Perhaps you can use that to navigate to your dashboard settings to change the language?

Don't know if such a setting exists, though...try it and let us know.

Edit:
So, if with your previous head unit, that's where the language settings were found and not directly through another method, then the head unit that replaced the factory head unit should provide those functions.

For the TEyes CC2 and CC3, once the proper Canbus setting is specified, I believe there is a Car Info app or something similar, that provides access to vehicle specific functions/settings. For the CC2, which I have, there are additional menus that are available in the normal settings when you specify a Canbus adapter. Have a look around your settings to see if you can find anything like this.

Question...did this just start happening or is this the first time with the head unit and the Chinese text in the dashboard is showing up?
Question...have the head unit language settings been set to the proper language?

Issue is. Supplier sells unit with CANBUS for generic GM as Chevrolet to European cars such as Opel Astra. Settings for canbus is GM/Cruze/cruze_manual, and kinda covers most of ECUs. In settings under 3368, settings for language don't exist. It covers basic personalisations, lights and doors, not nothing like that. At the moment decoder is by HiWorld. I got GM compatible one from Rise but don't know how to force unit to recognise it. When I connected it in canbus settings i couldn't na choose Rise. So I got an OBD OPcom/vauxcom and will change language trough that. But thanks for the tip with translate. I know that display by memory, it's just annoying to see avarage consumption as bunch of lines putted together.

Problem jest. Dostawca sprzedaje jednostkę z CANBUS dla generycznego GM jako Chevrolet do europejskich samochodów, takich jak Opel Astra. Ustawienia dla canbus to GM/Cruze/cruze_manual i w pewnym sensie obejmują większość ECU. W ustawieniach poniżej 3368 ustawienia języka nie istnieją. Obejmuje podstawowe personalizacje, oświetlenie i drzwi, a nie nic takiego. W tej chwili dekoder firmy HiWorld. Dostałem kompatybilny z GM od Rise, ale nie wiem, jak zmusić jednostkę do rozpoznania go. Kiedy podłączyłem go w ustawieniach canbus, nie mogłem wybrać Rise. Więc mam OBD OPcom/vauxcom i przez to zmienię język. Ale dzięki za wskazówkę z tłumaczeniem. Znam to wyświetlanie z pamięci, po prostu denerwujące jest widzieć średnie zużycie jako kilka połączonych linii.

Your problem is very simple to solve. Just go to the "Vehicle Settings" tab and there is an option to change the language. I will try to send the photo as soon as possible.

Well, there is no setting for an language for dashboard of the car. only for the language of the HUD. but thanks. im trying to get update from manufacturer.

At first, my car spoke Chinese too. Managed to change on the menu

Well.... It's not that easy on my unit. Or maybe decoder is wrong. Basically no language setting. And most of settings are empty screens. Canbus is set as a Chevrolet Cruze. I have a second "Opel" canbus unit but not sure how to connect it. Does it require reset if the HUD or is it plug and play?
