My 9500i detector doesn't ouput the sound alerts anymore. I switched it on and off several times and made sure to raise the volume to the max with no luck!! anyone knows what the problem might be? I hope it's something easy to fix in the programing or something as simple as that!!! as I don't have time to send it back since I need it for my daily commuting trips!! I think I would loose my license in one day if I don't have this detector in my car!!
