Okay, this is becoming a dead horse that we are beating to “graveyard dead” status. However, here is my 2 cents worth.
If you plan to use the unit as a backup, the Pilot III would be better because you can stick it up on the dash and still read it. The 195 will need to sit in your lap which will probably require that you attach the remote antenna. All while dealing with the “emergency”. The Pilot III’s attached antenna works well if you sit the thing on the dashboard (same for the 295).
Therefore, buy the Garmin pilot III (better economically if it is going to be a backup soon)or if you want to splurge and own the best, the 295 and enjoy it until the SR20 is in your garage.
After that delivery I suspect you will never use it again unless some maintenance delays cause you to have to rent a spam can.
I fly different kinds of airplanes. I once had an owner ask me why I had my Garmin III on top of his dashboard. His panel was 5 EFIS tubes with FMS and all. I was on a demo trying to sell the airplane. I told him, that if everything else goes, I can still fly with the Garmin III. He was not too happy, but bought the bird anyway.
I’ve also installed a 295 in the cabin area of a Cheyenne, works great without a remote antenna, I mounted in between the two windows and supplied with power Great unit just using too much power for the color. Great unit if you like big things. The Garmin III is small, you can take it anywhere, you don’t have to worry about running out of power, I have used it for 15 hours on 4 AA, it has everything plus some, it is not in color, but if someone buys mine I would buy another one without thinking twice. Things that are important to me are in order. 1. Easy to use. 2. Battery life. 3. Must be very portable. 195 is nice, 295 even better but they do not pass the 2, and 3 priority on my list.
I do believe the Garmin III can be used for international, just upload the international data base and you have it. I have used mine from Canada to Sao Paulo Brazil and it has worked fine 100% of the time, and I have not noticed any errors yet. Except once, I could not get the satelittes, I trouble shoot the problem by installing the antenna, for some reason it would not work without it. ahahahh!!!
Have a great day.
PS on the way to Palm Beach, FL for the new year
I advice the Lowrance Airmap 100 as a backup in stead of the PilotIII (I got it for $ 525,-), all Garmin options are standard with the Lowrance, plus it has an international basemap. The database is either Americas or International. For international use, You have to buy 2 Garmins !
