Has anybody ran there TR-1 using a waypoint on there GPS? Just curious how well it works, if it stays on track? I have a TR 1 Gold runnning my Kicker and have it phased into my Lowrance LCX 113, but have yet to program it to run on the GPS, it's wired in but not real sure how to set it up. Have tried to get code 48? to upload but seem to get no response.
