The G3X started out available only for experimental aircraft. And finally, for the top of the line, go for the G500 TXi. If you want a little more, then go for 2 GI275s little more then the G3X. So, if you want to be a minimalist, go with 2 G5s. I like the flexibility of having the second GPS. I'm very happy with the G5.Ī lot of people go with the GNC 255 in lieu of the GTN 650 as a second radio. That wasn't enough for me to want to upgrade to the 275. In regard to the G5 vs the GI275, the G5 has some additional data displayed, but the GI275 has a brighter display. Garmin also gave a discount for the upgrade if the display was returned. The upgrade from the G500 to the G500 TXi was a little more extensive, but only took a couple of days and a new left panel to adjust for the increase size of the TXi. It was simply an exchange and system upgrade. Unlike the G1000 where upgrades are either expensive or unavailable, I took advantage of the ability to upgrade my system from the GTN 750 and 650 to the Xi versions. With the TXi, GTN 750 and 650 there is overlapping of data, but I find I can make use of all of it by putting different data in the various data fields on the different products. Since I wasn't going to upgrade to a turbine airplane, I decided that I would go all in for the best that Garmin had to offer.

The TXi is more expensive than the G3X.įor me, even though the G3X wasn't available when I did my installation, I'd have still gone with the G500 TXi. Those capabilities do come at a price, though.

The interface of the G500TXi has more flexible capabilities for future developments. While the G3X is a very capable glass display, its interface capabilities are rather limited. We don't know what the future holds in avionics.
