Steve: So far I haven't tried it in the aircraft as it is still under construction. I did however look into the speed problem you described = before purchasing the unit. The only difference between the GlobalMap 1000 and = the Airmap 1000 were; 1. Position of the buttons, right side for air unit and along the bottom = for marine. 2. Lowrance no longer sells the GlobalMap 1000 as they found that they = could get a lot more for it by placing the word air on the face. 3. programming. Both units use the C-Map chart base and the world base = map is factory installed. 4. The old marine unit used big cartridges for updates and the air unit = uses those little data cards that we use in digital cameras. Took some = looking around but I found a NOS cartridge unit as well as the cartridge to SD = card adapter on e-bay and bought the pair for $20. I now have a grand total of $100 invested in a large screen unit that I don't need a magnifying glass to see. First time I get a chance = to hop a ride with someone I'll take her along for the ride and report back = on operational status. Nothing ventured nothing gained.

It turned out that the terrestrial units had a max speed limit = (something=20 like 50 mph). Question is if your Airmap is the same and /or if a=20 re-program to aviation software will remedy this.
