I have reactor 40 kicker. With lowrance hds 12 setup. My lowrance hooked up to Nema 2000 will allow the reactor to do software updates. As far as following tracks. I think you have to have garmin fishfinder/mapping. It also may have to be a higher end garmin to work. This was found on garmins website. Auto Guidance is a feature only available with Garmin compatible chartplotters and premium charts. Auto Guidance builds a path the vessel can follow to include turns, overhead clearance, and draft considerations, and how close you want to be to the shoreline.
