So I finally got my Here GPS installed. Pretty simple affair. I tend to be more of a function over form guy, so I designed a simple mount for the new GPS antenna. It Velcros to the Stock GPS cover so it can be removed to fit in the backpack. The mount is exactly the same diameter as the foam mount that comes with the new GPS, and is tall enough to lift the HERE GPS mast above the prop arc. In the event of a crash, the Velcro will hopefully release and prevent any damage. I bought the "replacement" GPS cable from mRo and cut that up instead of cutting the stock cable. The pinout i used was from earlier in this post. Worked great out of the box. I did not use the compass in the HERE, so the stock one is still in use.
