Hi everyone. Newbie question. I will be travelling across several states and I could have sworn that I saw a feature that will allow the scanner to constantly receive frequencies as you travel without having to keep adding info into the scanner. I don’t believe it had anything to do with GPS capability (which I do not have). I have three manuals; the one that came with the unit, the “easier to read” one by Mark Lauretta, and the Nifty Manual. Can anyone help me locate it, or was I just dreaming? Thanks in advance.
