Alpines CDA-9855 represents the next step in the evolution of the in-dash receiver. Take a close look at CDA-9855s faceplate, and you might find yourself saying in surprise, "hey — there are no preset buttons!" And youre right — instead, theres only a simple, white, silicon rubber strip. Thats Alpines incredibly innovative GlideTouch™ panel. Just like the touch pad on a laptop computer, you simply slide your finger over the strip until youve found the function you want (a sound guide helps you out).
