Hi, sorry if this is old, but I'm new to the forum.
My JY-UMS04NV uses the default Radio app v1.0. It comes with some FM stations already preset, but not to any frequencies that work in my area.
But I cannot change them and store them permanently. If I re-tune, then hold a preset button down, it seems to store ok.
But when I turn the unit off and on, all the presets revert to previous stored settings. Is there a way around this please?
