40,000 ft altitude with the Garmin Nuvi 265WT GPS on a commercial flight / plane

We sneaked the Garmin Nuvi 265WT GPS onto a commercial flight during take off and at cruising altitude to see how well the tracking would be. Just like with the private jet in the previous video, the Nuvi performed like a champ. Although this time, we didn’t reach the 600 mph but did get up to around 40,000 feet.
