I can speak at the moment about the LX Navigation Eagle. Stay away from it for now, the support as of March 2019 seems non-existent after filing tickets and multiple reminders. The only reply was a promise to get to it without follow through. Perhaps they will staff up at a future time. My issue was what I believe to be a defective unit with inactive Rx/Tx adter what I believe to be proper firmware prep and proper wiring. I am returning it for a PowerMouse.
