Trying to get my GPS up and running on my new to me CF-19MK5 . I installed GPS Viewer. Set com to "3" and baud rate to 4800 and click start GPS. Press 'Hot start" I get "3 blue" and '10 red" . On "Cold start I get "12 red and no blue but get 5 in a red box , top line ?? I am using an old GPS from a MK2. Hopefully will pick up something new soon.
