Thanks for your suggestions. I took my bike out while ago and the audio will come in over the Cardo with the music off, but the volume will not turn up even with the control rolled all the way up. I can't find a volume control with the Google maps like there is with the music. If I want volume, I may just have to have the music on. I just re-read the post above. I will try to turn the music up and then pause it and perhaps the Google maps will mail the higher volume... Thanks again.
