Adding external buttons

[Txori82]

Hello everybody.

I have a big problem with my installation.

The original radio is this:

IQ Navi




But I have modified it to this:






The problem is that I need to add external buttons to control the radio. Tipical volume, next song, home...

I tried with an USB keyboard, the problem is that this USB keyboard only controls Android. Volumen for example, I can control Android volume but not output amp so in the radio doesn't affect the keyboard.

Any idea?

I suppose that there have to be any option on the motherboard to add external buttons.

This is the moderboard.




Thank you very much!

karogs, тебе для тестов?

I'll try putting 14 resistor of 2k.

My doubt is if original steering wheel control will continue working...

Txori82, Потом расскажете , что у Вас получилось)?

Now I have the steering wheel from CAN BUS.

Is a BMW E92

[Мамай72]

There is a solution

[Txori82]

No no,

My car has Steering Wheel control and works OK.

I need to add more external buttons. I have to convert the old BMW radio in control for the Android Radio.



I'm going to use this original radio to control the Android in addition to the steering wheel

I have install Android Radio on the original radio.

Всем привет! Есть у кого-нибудь успех в данном деле? KEY1 и KEY2 нужно замыкать на массу чтобы получить рабочую кнопку?

По-правде сказать несколько шокирован идеей ТС.Зачем,зачем менять шило на мыло?Понятно,что оригинальный ССС не очень,но есть же CIC, там и жёсткий диск,и,что немаловажно-БК,без которого на этой машине сложновато.Мало опций?Ставишь Комбокс,и у тебя появляется БТ,ЮСБ и прочее.Не нравится CIC,можно поставить NBT от ф-серий.

I'm really happy with Android Pure installation. No CCC, no CID no BMW system. Only Android , Radio, BT, MP3, Cam...

Hello,

I have been looking the cables, and I only have KEY1. Key2 and GND goes to CanBus box. Is this usual?

I can use any ground and connect with Key1 to do the buttons?

[Txori82]

Any answer please?

I'm finishing the upgrade to 6 and I'll like to take key lines out before install the radio again in the car.

Thank you!

Txori82, solution is very simple. I have similar case. If CanBus box is only used for steering wheel controls, remove it and use KEY2 by yourself. Use KEY1 and GND with different nominals resistor to achieve different buttons.

Sorry but I don't understand. If I remove the CanBus, how is going to work steering wheel?
