Another note I remember now after reading your post I only put 1 out of the 4 screws on for…"

"Brad, my problem was I was trying to plug the GPS into the new style connector on the top but I had an old style GPS cable that plugs in on the side. I damaged the pins but replaced the cable and got it working well... Until I crashed my plane last…"

"As I continued to play with the hardware this evening I noticed the blue "Fix" LED does blink, but only very dimly in a fairly regular pattern. The voltage is not enough to fully illuminate this LED, but if the lights are low enough it can be…"
