Why don't you guys just take a look at Desktop Aviator's Model 2450? It has all the switches you need for a Garmin 500 along with a Dual Rotary encoder. And it also has a 4 by 3 inch high resolution screen. All this for $228.00usd No Ipad needed http://www.desktopaviator.com/Products/Model_2450/index.htm

A wrote to Bobby B. of Desktop Aviator and he tells me that they have a new Parking Brake using a real Parking Brake "T" Handle. It is mounted inside one of their Gray Plastic Cabinets with 2 additional toggle switches using a modified 2120 pulse generator. I do not know the price of the panel, you have to write to Bobby for that at: support@desktopaviator.com Here is a photo he emailed me. It runs off of your computer's usb port You can see the Panel at: http://www.desktopaviator.com/Products/Model_2400/index.htm
