Mixed results..latest was a walk.. excellent result with voice commands coming through earpiece. In car really awful no sound so hard to follow..visually far too dark in sunlight 2nd time same problem, eventually sound came on..& yes it wasn't muted, although it started that way auto have no idea why, want that annoying voice & yeah would prefer male voice as not so whiney & I'm female so maybe just prefer listening to mail voice.
