You need to have the esp32 in the car all the time as it acts as a gateway between the VAN bus and the CAN bus.

I understand, I'm going to start assembling the board, I ordered the printing of the PCB in China at a lower cost, in the end with all the components the cost is a little high, but having the new CB will be worth it :) Very thanks for public your project and congratulations for the excellent work.

Hi Peter
https://github.com/morcibacsi/JunsunPSARemote
It will work with van can bridge also?

If you order a Junsun headunit for CAN bus cars you will get a Raise CAN box. If you connect this box to the CAN part of my VAN-CAN Bridge it works (temperature, and remote controls at the steering wheel, display brightness based on the headlights). However with the help of the library the VAN-CAN Bridge can be left out as custom software can be made to translate the VAN messages for the Junsun unit. For example my PSASteeringWheelAdapter could have an extension for remote control.

Hi Peter,
I have seen some bridge firmware updates. Can you tell us what other improvements are you planning?
Will the problem with the reset button ever be solved?

Hi,

Yeah, there were some issues reported by users which were quite annoying to prevent the usage of the device for them. Recent fixes included a function to read the VIN code from the radio. So now it isn't necessary to know the VIN code of it, and one doesn't need to have access to a car with CAN bus, and diagnostics interface. Another hotfix needed to be released because in some cars the door status was flickering (again :(). And also with some odometer brightness setup the display was blinking. These issues needed special attention.
Currently I work on some code refactorings, to support a new type of board, which could be more compact and professional-looking. The reset button fix is definitely on my todo list as that might be the last one to have a full conversion (that might be the next one to fix after the code refactor). Also trying to make the TSS461 VAN protocol driver working instead of the TSS463. This should be done because the TSS463 will eventually run out of stock and the TSS461 can be scavenged from old displays, and odometers. There are two other things that I would also like to implement. One of them is to support the RD3 radio with the new display. And the other one is to support the newer navigations (RT3/RT6/RNEG, etc). However this has low priority as I couldn't figure out the messages for the compass on them until now (It is calculated somehow from the wheels rotation speeds and its differences). It seems like a tough job.

Edit: BTW the source code is there... contributions are welcome. Feel free to implement the features you miss the most.

Unfortunately it isn't. There are such devices for RD3 as well. I am sure you can find them on aliexpress, or ebay or some other similar sites.

Hi Peter,
After the last update, the car goes into economy mode when it is closed, the radio and display of course are off. Do you know this problem.

The reset button now works, but when pressed and held before the milage resets, the computer reads into a loop. Do you think it can be made to look like the original?

Fixed it yesterday.

I am well aware of that issue, but one step at a time (you just got the reset functionality working). After the reset is done, you can go back to your favourite page, so it isn't a deal breaker. Eventually it might get fixed, but as I said before the code is there for everyone to make it better. I like working on the project, but you have to understand that I work on it in my free time. Demanding new features and fixes won't exactly help in getting updates faster.

I understand it 100% and big thanks for this project.

I released a new version which should fix the issues with the trip reset functionality. Updating the TSS463 library to v2.0.0 is also necessary.

Hi Peter.
12 pin emfs are quite expensive and 6 pins ones often cost half as much, so do you think this display will work?
of course, if I convert the plug to the one in the picture and attach the pins

Hi,

Unfortunately it uses a newer protocol, so it won't work. When I find the time I'll try to add support for it.
