I use the steering controls mostly as well. I was just installing the screen protector and saw the knob was the same style as a previous Tacoma that I did the Rav-4 mod to so I figured why not.
The only complaint I have about the steering wheel control is no push to mute and how slow it can be to get the volume down. It's painfully slow. It was pretty slow on the RAM I traded in too, but definitely not this bad. Never had any issues with FORD's that have this feature but the Toyota's and RAM's are way too slow. So if I want to quickly turn the volume down I pretty much have to ignore the steering wheel controls.
I assume this knob is backlit too but I didn't test it. I forget. During summer months it's never dark at the time I drive and I never remember to check these things once it gets dark out.
