Android radio for astra h - Where to connect key1 key 2? Do can h can L does not work

Hello. I have a problem with connecting the steering wheel control - after connecting key1 and key2 to can H and can L, nothing happens. Does anyone know how to connect it? Regards

Nothing like without a CAN converter. Key 1 and key 2 work on the principle of resistance between them.

These cables cannot be connected there.
My magic glass ball broke, so I can`t conjure anything from it. So you will need to provide more details though.

What is your factory radio model, what Chinese car did you buy? Photos, including plug wire harnesses, are welcome.

I wrote the solution above, so there`s no point in going further. You just need to know how radio controls worked 10-15 years ago - resistance. In this radio, a given resistance is assigned to a given function in the settings.

Hello. The original radio is cd30mp3 and the Chinese radio is android 8.1 has no name. I have three problems if anyone could help, namely: 1. The radio does not turn off, I connected the ILL cable to the positive of the cigarette lighter and installed a switch in the ashtray, so I turn off the radio, otherwise it stays in sleep mode, the date and time are displayed. Or should I connect the ILL cable to the ANT like the REM cable from the amplifier? 2. The reversing camera works until I start the engine, then there are interferences and after a while there is a black screen. I connected to the cable from the bulb to the reverse light. Should I connect directly to the socket or where? 3. This most important steering wheel control. Do I need to buy some module or what? Thank you in advance

Together with this radio you should have a CAN BUS adapter with wiring harness. Something like this topic . Of course, you may also have such a problem with the radio because this BID display is linked to the original radio, but never mind.
The ACC and ILL wires can be connected together and in your case they must be. In the rear or front fuse box, find the power line that appears only when the key is turned to position 1. Run the wire through the 5A fuse to these two ACC and ILL. Well, now that I look at it, you can also connect speakers and, in fact, power the antenna. Connect the camera to the connector marked No. 4. Under the brown signal from the reverse lamp, directly or through a relay and power supply, e.g. from the cigarette lighter. Anyway, this is not a radio dedicated to this car model, I would sell it and buy something else dedicated and adapted with the frame and everything else. I leave the decision to you.

Thank you very much, on Saturday I will start connecting it as you wrote. Unfortunately, this can bus was not included in the set, but I will look for it on the Internet. You also wrote that I should connect the ill acc and ant speakers together, but they are connected directly to the speaker cables from the car, only the central one is connected to the left front one. I have ordered the frame for the radio separately, I will install it and everything will work, but it will probably take some time

Please, entrust this connection to someone competent...

Hello.
I don`t know if it will be helpful because it concerns another Android radio in Fiat Bravo2, but I had problems with assigning functions to the steering wheel control buttons. The problem was solved after cutting 2 wires from the harness under the steering wheel transmitting the signal from the buttons and connecting them to KEY1 and KEY2 from the radio. I`m not writing which wires these are because yours probably have different colors/markings... but maybe it`s worth checking this lead After this connection, steering wheel control works 100%.

the description of your original radio is:


unfortunately it`s CAN

Either an adapter or combinations, if I`m not mistaken, the remote controls are still analog, but later the signal is changed to digital. You would have to pull the cables from the buttons, make a board with resistors and then connect it to the new radio. The matter will not be simple because the remote controls are in the steering wheel and not on the column.

I`ll refresh the topic a bit and ask if anyone knows how to control key1 and key2 in the new Chinese Android device on a separate board with resistors? I`ve been looking for a diagram and the values of these resistors, but I can`t find it.

1.2K, 1.5K resistors should be good.

If my memory serves me right, it doesn`t matter whether key1 or key2 does not have to be both.

It won`t be easy to plug into the remote control buttons on the steering wheel and pull the cables.

Maybe look for CANBUS BOX adapters for Opel radios on Aliexpress.

Good point, you could probably create a makeshift set of contactors with resistors from the contactors yourself to make sure whether the game is worth it, anyway, purchasing a Canbus adapter for a specific brand seems to be more reasonable.

I also found such a schedule for the Chinese.

Thanks for the tips, I need a CANBUS BOX for a Mercedes, and these are quite expensive and don`t always work

It`s also true that the Chinese often don`t know 100% whether his equipment will work, but he always pretends that it definitely works. Either way, the decision is yours.

I just want to make the controls on the central tunnel at hand so as not to reach the radio, and connecting these inventions to the steering wheel ended with the lights on and an SRS error. Other solutions are too expensive for this car.

Hello

I would like to reheat the topic of Key1 and Key 2
Opel Meriva 2004 versus Chinese
There are 5 wires coming out of the radio and 2 wires coming out of the chine's cube plus two loose wires marked Key 1 and Key 2.
The wires of the chine's cube cover the android radio to the astra h - Where do I connect key1 key 2? To can h can L not work 50% with the original cube
Anyone perhaps already worked through this?
.

I think the steering wheel control in the Meriva is the same as in the Astra G, i.e. resistive, there was already a description of the connection somewhere on the forum, you just have to search for it.

Afaik the cd30 radio uses resistive buttons on the big connecter under the usual power and speaker connectors, its 2 wires, one is SWC (Steering Wheel Controls) and immediately next to it is the ground for the controls.
connect these to your new head unit, SWC to key1 , gnd to headunit ground.
Can l-h on these radios(cd30/cd30mp3) I believe is just for the lcd display.
I'm just fitting one myself and was wondering how the SWC worked and I know this thread is as old as I am.....
