Sam: Have never had a problem reading my iFly 700 in my PA-22 and I have tried it in several mounting places (see pictures in the photos section of the forum). I also have a Garmin 295 (color) which washes out completely in direct sunlight, but the iFly has been consistently readable for me. You should know that when using the Sectionals and Terminal Area charts display modes that the actual FAA charts appear with the same muted intensity as the paper charts - it is not the fault of the iFly but rather that the FAA just does not use vivid colors on their maps. All the readouts ("Instruments") on the screen are always readable; and all the other display modes (Vector, Weather, Plates and Airport Diagrams) are as vivid and bright as any other GPS you would use in your cockpit. No regrets, in fact, just the opposite - I am very pleased with my iFly. And, in my opinion, the AP customer support is unparalleled - superlative, actually.. --Ralph .
