I have a panel mounted Garmin 496 with the antenna out on the wing, and an ipad mini running skydemon on a Ram mount up on the roof crossbar like a car sun visor bluetoothed to a Garmin Glo, both really good pieces of kit, if one had to take a dump, i would prefer it to be the Ipad/SD
The 496 (permanently mounted with a properly mounted external antenna) is a rock solid device
