Here's the inside of mine.
Update on my gps: I got a new one and this time I'm trying the flush mount. So far tests are promising. Testing in my backyard, I got full lock even with it right next to my Contour cam. That is without my AV Tx plugged in. When I plug that in it drops to 1 red blink, 1 green, which is pretty much what I got before with the stalk mount. Hopefully today I'll be able to test in an open area. I'm hoping I don't have to do any shielding or use ferrite chokes or any of that. With this same setup and the gps mounted on the stalk, I never had a problem getting full lock.
