I am currently looking to purchase a plane with dual Garmin G3X NON Touch units installed. Since I have only used garmin handhelds of the outdoors type, and rarely used their aviation units other than an old 95XL that is now garbage. I am oblivious to what is good and bad about them. These G3X units are 2013 vintage (my guess) and I have read that they might be close to being outdated since they are the 'NON' Touch variety. Also, have read that updates of maps and other updates can make some of the older Garmin units obsolete. I don't really fly enough to warrant spending a lot of money on the maps and updates. Most of my flying(99.9999%) is over rural land and out of private strips. Are these still a good unit or best sold for an update. I only fly VFR but my son wants to get his IFR.
