Power Mate Volume Control Install!
Now this is probably the best thing I've ever done to a car! It's a Griffen PowerMate which is basically just a nice big volume knob off a stereo only this one is USB. Turn for volume, push to mute/unmute. It's right where I can reach it with my right hand. So simple! I love it! The only bad this is the darn things costs $50!!!
