We took the Garmin Nuvi 265WT GPS from take off to cruising altitude and speed in a Cessna 750. The tracking worked great and we saw the unit go up to 625 mph although the video only showed around 500 mph. It was fun comparing the Nuvi to the in-flight map because we got to see our flight moving over roads! However, while the speed were comparable, we noticed that after above 10000 feet, the altitude didn’t match the in-flight map by as much as several thousand feet (at 25000 ft). We assume the in-flight system is more accurate. See the video response titled “40000 ft altitude …” video where we take the same GPS but recorded its usage on a commercial flight. www.youtube.com
