Don't remember seeing you come by, I work in the install bay for fun part time. Have them send it out, they need to clean the laser for you... Other than that you could attempt to open it yourself and clean the lens, but I wouldn't recommend that.

Another thing, If you can afford the extra 20-30 bucks next time you buy a headunit, don't waste your cash on a friggin Aiwa just to save a buck, cheap ass
