I am a total novice when it comes to ripping apart a bike to install anything and usually let my local shop do the work. In this case I decided to try it myself. Took some time and a bunch of you tube videos to dismantle a few things, but in the end everything worked out. I have a 19 1250GS, and I ported over my old Nav 5. The Garmin did the job, but it was slow, and felt outdated. I purchased the Chigee for the Apple car play and wanted to use google maps, and Apple maps. Did not really care about the camera features, but after install, I am really happy that I now have front and rear camera recording. The car play features work seamlessly. I also installed the control mod for the wonder wheel, and it works well to control the entire setup. Its been over a year since I installed, and I wanted to wait to write my review in case the setup fell apart. Happy to report, it just works. Much much better than the old Nav setup. All the wires are hidden, and looks like a part of the bike. Wish I had also purchased the PSI mods for the tyres, but I will grab those another time. Great product. Take your time doing the install, and you wont regret your purchase.
