I agree with Garmin as well. I have three GPS''s, a Garmin, a Raytheon, and a Magellean. At least to me, the Garmin is far more intuitive to use and much quicker to move around to the various functions. My Garmin is an older model so the Raytheon seem to boot and acquire faster but it also has a rail mounted antennae vs the small patch anetenae of the other two. The new Garmins lock in way faster than my older one.
The only problem with the old Garmin is that although a dated, it is so convenient and so compact that although I have two other GPSs on board the I still carry it on board because I like the way it works and so I use it out in the cockpit rather than the built in system which I will probably continue to only use with the autopilot.
