Question Remap TEYES T-Pro Steering wheel buttons

Search This thread


Nov 23, 2012
Hey guys. About a year ago I installed a Teyes T-Pro in my '14 Focus ST, and while its better than the ST1 radio I had with a 4" screen, I hate this thing. An entire 1 inch vertical segment of the screen does not work, the screen does not turn on when the ambient temp is below 50 degrees F (until it heats itself up, takes like 25+ min in winter), subwoofer pre out doesn't work, and many many more stupid issues.

The reason I'm posting, though, is I would like to remap one of the steering wheel keys. The built in app to do this, of course, does nothing. Apps like button remapper also do nothing, probably bc the buttons function over CAN-Bus. When I press the microphone button on my steering wheel it opens an app called "car-info" which also does almost nothing. I am wondering if there is a way to have another app (google assistant) open right after this "Car-info" app opens. Also, if anyone has any experience with the T-Pro any input would be very appreciated. TEYES Tech support never responded to my multiple messages, of course, and I can't seem to find a head unit that sucks less and I don't want to roll the dice on another Teyes product.

Any input would be greatly appreciated...
Thanks a ton

What kind of car do you have (year, make, model, etc)?

Did you install the T-Pro yourself?

Do you have schematics for your car? If so, how do your steering wheel buttons connect to the old head unit?

Can you tell from the schematics if the buttons are resistive or not? Only resistive buttons can be remapped.

If your SWC are resistive, then you should be able to directly connect those buttons to the T-Pro inputs...I believe they are labelled key1 and key2. If the SWC are not resistive, I don't believe there is anything you can do about remapping them.
