I got the SM10 to connect my non-bluetooth GPS but now I cna't use my phone for music since I can only connect it or the SM10 at one time. I though I could then use the SM10 to connect both with the phone on the audio input and the GPS on the Aux, but this configuration makes the Aux inpu useless as it cannot be heard over the music from the audio. I would like to have the music on the audio muted or at least the volume decreased so the GPS can be heard. Otherwise this unit is going back since I can't make any use of it the way it is.
Have the ability to set the Aux input on the SM10 to mute the audio input for GPS priority over the music source.
