, I learned that the primary difference between Aviation GPS's and Non-Aviation rated GPS's such as Marine units is the times per minute that they update. > The Aviation units update many times more per minute than ground or marine based units. >Scott Cable +++++++++++++++++++++++++++++++++++++++++++++++++++++++
I have a seven year old Lawrence 300 and recall reading in the manual when I purchased it that the unit can be set to update once every five seconds or once every second. I guess I'd better check what mine is set for now that I'm using it in the KR. I may be there already !!! :-) Larry Flesner
