Unfortunately at first I couldn't get connected via ethernet as I just couldn't get the adaptor to 'enable'. With extensive Google-fu I managed to find a solution that worked and now I'm flying It doesn't take me several attempts to download the full sized maps now. I can go on a repping frenzy so watch out!
