Review on Effortless Car Control: PolarLander Universal Wireless Steering Wheel Controller for Music, DVD, GPS Navigation, and Radio - 4 Key Remote Control Buttons in Sleek Black by Dave Goodman

I can't get it to work properly. Some buttons work, so I know it's communicating with the stereo. The working buttons are mixed up and don't control the function they are supposed to control. I should be able to reprogram the buttons through a two din stereo, but my stereo doesn't have that capability. I asked the manufacturer if we could manually reprogram the buttons but they didn't help. I've been waiting to install and fix this issue and now it's no longer a return date. I am extremely disappointed. For me it's junk now and I can only throw it away.
