I avoid all these connectivity problems with my Tekonsha RF, their top-of-the-line wireless controller. I originally used the factory wiring on my W164, then switched to the RF. It seems to work better, especially at low speeds, like gas stations.
I used it in our W166 (which I also added the pigtail to the factory wiring in case I wanted to pull a friend's RV).
I haven't pulled our RV with the V167 yet, but I haven't experienced any of the "problems" in RF pairing reported by others.Tekonsha engineers are readily available - knowledgeable and helpful.

I recently got a GLS580 (I am in Canada) and it came with the factory hitch. I was at a RV Trailer dealer yesterday, was going to try to tow by using Curt Echo . The Echo didn't get any power and I am wondering if it is the same issue you had that the Manual Park Brake needs to be on for it to receive power. The unit briefly turned on for 2-3 seconds when I connected the trailer's 7-way connector to the Echo but went offline again.
Did you had to install any fuse or anything at that #436 spot? Mine looked identical to yours (without any fuse).
