When I select mp3 mode, my RNS-E immediately starts playing the first track on the card. If I want to select a particular album, I have to hit return to exit to the artists' list. Is there a setup menu option I can set so that when I enter mp3 mode, it displays the top level directory of artists by default, and doesn't start playing immediately? Second question. When my phone is connected via bluetooth, does the five-bar signal strength meter reflect the bluetooth signal between the phone and the RNS-E, or the airtime signal between the phone and the provider?
