If you don't like the digital maps on Pilot or Foreflight, you can set them to display sectionals. You just have to make sure the charts you need are downloaded. Brightness of display can be adjusted, both in Pilot and on the device itself.
If you are using polarized sunglasses, that is the problem, not the device. The only time you need polarized is on the water. If you have old geezer eyes like me, sunglasses with reader inserts like these are awesome:

I'm trying to decide on my XC setup for my new Super D. I have a GDL-50. When I rented a 182 for VFR XC, I flew with a panel-mount GNS 430 as primary and a 10" tablet running Garmin as alternate. The tablet pulled GPS WAAS and ADS-B weather and traffic from the GDL-50. I carried a phone also running Pilot with built in GPS as contingency. Emergency nav was VOR, visual reference, or pilotage. PACE.
For the Super D, planning on flying with GDL-50 feeding GPS WAAS to tablet and phone. Am wondering whether I should consider buying an Aera 660. Seems like that would be duplicative of the GPS and AHRS capabilities of the GDL-50, so the main reason to get it would be increased reliability over tablet and phone. Thoughts?
Also trying to decide whether I trust AHRS on the GDL-50 enough to get out of inadvertent flight into IMC while on XC. I have a habit of delaying departure and turning day trips into night flights for the last 30 minutes. In theory the electronics in the GDL-50 are the same thing as I would get in an electronic AI or PFD, but I have more confidence in a built-in AI certificated for IFR. I don't want to waste $3K on a G5 or RC Allen 2610 just on gut feeling, but a built-in AI would always be on and ready for use in an emergency, unlike a phone or tablet where I would have to take deliberate steps to set it up and put it on the AI page. Thoughts?
