Mine has never worked right, installed in my car, and even checked by a mechanic and it still does not do what it should. It forgets everything once the car key is taken out, so always in demo mode!! Very frustrating, hearing the same track on your CD in flat mode! Plus even if this worked, it seems not capable of numbering radio stations into its memory. And also takes my car time display off the dash, no idea why it does that! All in all, not a good buy and due to Amazons, 30 day return policy, I am stuck with it! Not happy!!!!!
