kbrkr posted a topic in NEX SeriesObviously, I did not install the speed pulse wire during my installation as I had a hard time finding the correct wire in my Porsche. I'm starting to get this error; "Calibration will start, but may be inaccurate without speed pulse." Whenever I use the Navigation. When the error is present, the NAV screen is unresponsive. It has to timeout on it's own. Anyone have a workaround?
