No, I have not just yet. I have not had the fairing off either yet. Have noticed that my headlight is aimed to the left quite a bit so it doesn't sit centered in the faring. Never ceases to amaze me. Either the factory isn't concerned about how things line up or dealerships are not concerned about how things line up when they do the setup they like to charge us extra for. So, I have to take care of that before I put the fairing back on. And can you believe it, I got the new bike sitting in my garage and the trade-in still sitting there while he was getting some paperwork. I gave the bike a quick overlook and what did I discover??? The left rear footpeg was nothing more than a common rubber footpeg from a Heritage. I thought, wt?

I brought that to his attention and he said, "that must have come from the factory that way". Not!!! so, he allowed me to swap out footpegs so at least I have all the stuff I'm supposed to have on the bike. Ha!
Back on the subject of where am I going to mount the plug for the GPS??? I may just go with a piece of velcro inside of the saddlebag and put the plug/GPS unit inside a small, durable watertight bag and attach it to the side of the saddlebag out of vision. I don't think there is room inside the "jockeybox" in the dash. Think that is full of "fuse" if I remember correctly. Have had a few back aches and pains since I got the bike and am sort of inching my way into knowing all about it.
