An external GPS is just one more thing floating around the cockpit (yes, I know you can secure it, sorta) and one more thing that either has to be connected to ship's power or charged frequently. Why would you want to do that?

Hang on here guys.
The Garmin 660 IS or can be your external GPS if you connect to it with your iPad via Bluetooth. I was sure this was true but just got off the phone with Garmin support to make sure I was being factual here. So, Mike, you don't have to have more than what you have. I'd be a bit surprised if that isn't the way you have been using it already. Once you connect you can go into the 660 Bluetooth set up page and have it connect automatically every time you turn then both on. You can see the connection in Garmin Pilot if you go to settings you will see a green bar next to your 660 in the equipment list on the left. I'm sure that Foreflight uses it as well but right now I can't find how to prove it. I am having trouble understanding why one would prefer to use the internal iPad or iPhone GPS. It has never been nearly as good as a real aviation GPS. Certainly OK to use in the car but really not for airplane navigation, though I'm sure gets you pretty close. It is not WAAS enabled your 660 is.
The much better set up, however, is to use a GDL50 series along with the iPad. Yes, the 39 works as well but the 50 series according to Garmin is considerably more technically advanced, and has a more advanced AHARS chipset and also does the ADSB in very well too. I am using Aera 660, GDL50R, and now the new iPad Mini 5 which I think is an extremely good combination. AHRS is very good on Garmin Pilot and ForeFlight, ADSB in is very good on both the 660 and ForeFlight and Garmin Pilot. The new Mini 5 is a very significant improvement over the Mini 4. It updates the charts very quickly no perceptible lag at all. The screen is brighter and very easy to see detail thanks to its new Retina display with True Tone and A12 Bionic chip. I have the 660 in the Airgizmos panel mount, the GDL 50 mounted behind/under the panel secured to the panel brace structure back near the firewall. Nothing floating around the cockpit most of the time except in more extreme turbulence.
