Look at this interesting remote control designed to be adapted to any car steering wheel.
Comes with control and a manual.
The control has this tab on the side to hold the steering wheel. There are several keys that can be programmed to perform any function of any remote control. This is a control with learning function.
On the back there are three leds that transmit the codes to several different directions.
Works with a CR2032.
See the control bound to the wheel of my car. I found a little uncomfortable, but you can use.
To program and learn other remote controls functions must tighten the SET button for a few seconds followed by the desired trigger button. Then use any remote control to transmit the code to be learned. At the end press the SET key again to finish the process.
I found a good product, too bad it doesn't always work. Learning has to be done repeatedly until work and depending on the angle the control cannot activate my radio. Anyway it is interesting for the price. I leave the link to the BuyinCoins website where you bought the product:
