I put an App on my D2 for sirens to entertain the grandkids, or maybe me. Sometimes when I, or the 5 yr. old applies the sirens, they won't stop. Going back "home" doesn't stop it either. The only way I can get them to stop is to shut the phone down. No, I don't know exactly which App this is, it has a blue/red light for the icon on the screen. Any suggestions on how to stop it other than shutting the phone down? OH- with it hooked into my truck radio via the MP3 cord--it's pretty loud. :rofl3:. Thanks, David
