I've been thinking, I know, it's a bad thing to do. It's maybe time to upgrade from a 496 to a 796 in my 7. What kind of problems am I going to run into with, #1, size, will it fit in the same space in the panel as the 496? #2, what kind of problems will I run into with the wiring? I'm feeding info to my AP and to the D180 and receiving XM weather.
