I am having trouble with the ATT (attenuating sound) in my radio. The sound goes in and out. The manual says this is a feature that you can press to turn down the sound fast, for example, if you need to use the phone. Unfortunately, mine turns down on its own randomly...sometimes it could happen 5 times in ten seconds. Really annoying. I have to press the ATT button to get the volume back. Again, and again, and again...I am wondering if anyone can help me with this. It is about a year old so it shouldn't be because it is old. Fingers crossed that there will be an easy solution!
