Hello, I like to listen to sirius radio while driving using the google navigation. Before the OTA update to JB they interacted perfectly, whenever the navigation voice would come on sirius would get quiet and I would hear the voice prompt. now what's happening is whenever the nav voice prompts to say something the volume is automatically down to 0. So I don't hear anything no sirius or the voice prompt for a few seconds until the voice prompt is done and sirius comes back on. When this happens I can press the up volume and hear the voice for the rest of the prompt but then the very next time it automatically goes back to 0 again so it's useless. I've tried uninstalling the sirius app to no avail. I am running stock android jellybean.
