It just so happens that I have the same radio. As a matter of fact, I bought two of those: one for an Integra and another for a Prelude. The Prelude one never had any problems, until it got stolen

The Integra one has worked fine. It is now on my new Accord. And still works fine. You should probably try to get another Alpine if this one is not working out for you. But one thing for sure, Alpine does make really good radios.
