CanBox versions

[Csabo80]

I had to replace the canbus box in my head unit because it wasn't working properly. The previous software is also used for the new canbus box. In such a case, should the first canbus software be deleted? If so, how and where can I find it? The two canbus boxes are not from the same manufacturer, so they are different.
The car's EV menu was not visible with the canbus set supplied with the aftermarket head unit. That's why I bought another canbus set, but I can't see the EV menu either. However, the second canbus set also runs the same can software as the first. It is fine?
My car is Hyundai ioniq electric. Out of curiosity, I set a completely different brand of car in the canbus setting, then the EV menu was visible. Why is that?

Thank you so much for your help. You were the only one to try to help me. Thank you very much

I have got all buttons swc working and doors and temperature show on the screen in my hu isudar

Solution: new canbus and new pinout

Hi, sorry for reviving this thread, however I have bought a very similar head unit for my Alfa Romeo 159 (PX6 with the DVD drive and the same Alfa fascia as yours).

I was wondering if your one worked without the key in the ignition? I like to use the radio without having the key in (as having it in the MAR position drains the battery much faster) however the unit turns off as soon as the key is removed or the engine turns off, unlike my OEM radio (which could be turned on or off at any time regardless if the key was present).

I think the canbox adaptor controls this, or the software side of the headunit does. I have the bagoo alfa-bg-01 adaptor which otherwise fully works with my steering wheel buttons.

Any ideas on how I could get the radio to work with the car off or without the key in the ignition? Thanks!

Impossible, as key ACC turns unit and starts canbus box which operates with car.

It qould be possible if red / yellow wires are to be swapped, meaning if you swap yellow wire which is memory or 12V constant battery wire with red one ACC key ignition it could activate but will be and stay activated even if car engine is off, possibly will drain its battery and battery will go dead.

Interesting, thanks. How does the OEM unit do it then? As it seemingly always has power (regardless of car power state) however turns off automatically when the doors are opened or when the key is removed AFTER the ignition turns off (remains on otherwise). I know the steering wheel controls did not work unless the key was inserted or the engine was on (after being shut off)...

Would be great to know how the aftermarket headunits work regarding turning on and off. Is it all controlled by the canbox? Or is it controlled by the software/hardware on the headunit? Is it as basic as a 12v input acting as a switch? I'd imagine it wouldn't be too hard for me to make some form of relay circuit/adaptor which could make it function as I desire while letting itself turn off at the right time.

Also, I know it has a sleep mode function as it lasts about an hour until it needs to do a full bootup (which takes a minute annoyingly each time). In theory it must have some power coming in to keep it in sleep mode? And if it does then surely it must have some ability to turn on?

Thanks

All I know of these aftermarket units that car ECU and canbus (dependent of car model) controls unit behaviour.
Canbus settings are to be correct with car model in factory settings in order to function correctly. As far as car settings and unit timeout, this is only to keep it in memory and run faster every time you stop like on five minutes or so and then go on again.
Canbus boxes and its software can't be edited or changed. They are fabricly set up for each car model.
One thing you can do only is to go to mechanic and perform diagnostic of car, put it on computer and then edit some car options like radio switching on /off etc.
For example my car Peugeot 308 has a battery life savior, it is called safe mode or something like that, thing is if radio works for like 15 min that system deactivcates radio and cuts electricity to it so basically goes offline and saves battery for startup of car. Unit can drain battery faster if non-stop online, remember that.

Hi, buy a new canbus box, this one is fried and cannot be saved. You can ask your seller to provide you with new one or buy it from ali express on your own.

 

[laser01]

my seller unfortunately is not selling this canbus anymore also is not selling either the radio it self.....did someone know how can i buy? searched on aliexpress but the same model is not available....the other canbus work well?

 

[alecxs]

yes, but you need to find proper replacement. share some pics and get macro shoots of pcb inside.

take image of both sides of your original canbus box and post here, we will find suitable canbus. name model of canbus also (go to info in settings and read canbus info there)

Here the photos

Don't you have macro shoot on your camera app? I can barely read MCP2515 the picture is worse

Better picture here

According to the software version on board , similar device is this Chinese IDOING on Ali Express, but you have to contact this store / seller of this canbus device and ask him correct model for your car model (like M. BENZ C200 year xxxx)
LINK: https://es.aliexpress.com/w/wholesa...idoing+canbus&spm=a2g0o.productlist.1000002.0

Also , if your modelof car is Mercedes Benz C200 or something else find your canbus box also on Ebay , type in your car model and canbus box and search for best fit (must be for your car model!).

Nope it's an Alfa Romeo 159....in fact I was surprise when I read "benzg"

Btw the 2 MOSFET in the upped side and one is fried the number is 4803A, and the lower chip is 5CL8.....

I was thinking to buy only the fried MOSFET 4803A and try the connection pin one by one.

before purchase check with seller of this canbus if it is proper for your car model (pin connector of canbus and wiring connectors for radio unit, etc. - if is 16 pin for canbus).
I think this canbus will do great - HIWORLD model , best at the market and compatible with all car functions.

you can try to repair. don't forget to reconnect drain on pin 7 on the left one.

i have speaked with the seller of that canbus box, he is looking if it's compatible....in the main moment I buy the mosfet 4803A and tomorrow i will solder with my air solder station with some flux paste......and i will solder also the pin 7 that has fried also.....
