Not all keys go, not on the steering wheel mountable

The remote control works with my Alpine. Not all keys go, but that will probably be due to the various car radio models. The key buttons (Volume, Skip, Fwd, pause, mute, source) go. A significant drawback to the use in the car is the fact that the remote control (qua infrared) requires visual contact with the radio. This diverse places divorced from the car. The remote control is to comparatively large, so that they are within sight really can not install on the steering wheel. The only sensible option is to place them in the field of handbrake / Gear stick. There, however, it works then, as it should.
