Hello,
I'm using a GMF6 box on my Opel Corsa E from 2016.
I have some issues with it. The steering wheel buttons, for example, they work, but the functions are wrong. For example the volume up button lowers the volume and volume down raises the volume.
Another issue is that I no longer have the cars warning signals, for example, the turn signal sound and the no seat belt on sound.
Can you help me with this?
Take care.
Opel Corsa E and Canbox GMF6
Re: Opel Corsa E and Canbox GMF6
Does this CAN module require an external speaker for the system sounds ? There should be a 2-pin connector in your cable harness for it.
Concerning wrong key assignment:
This is an annoying problem almost everywhere.
Unfortunately the head unit manufactures provide no or very limited possiblities to re-assign the buttons.
They could probably reduce the number of support request by 50% if they would add full button remapping capabilites to their OSes...
If you have luck, there's a hidden steering wheel learning app somewhere in your OS. But most learning apps support analog buttons only and don't work with CAN-connected buttons.
A self-made solution would be to create a small box with e.g. an ESP32-C3 SuperMini and put it in the serial port line from the CAN module to the head unit. Then write a simple programm that transparently substitutes the button IDs in the messages.
You can even write an extended software that adds support for double and long presses.
This will also work for the buttons of the radio control panel.
