I have a question. I downloaded maps from my area, and are now loaded into my Ifinder Pro. I CANNOT understand why my gps shows my location to be anywhere from 50 to 200 feet off the road displayed on the map? I am using an external antennae, and have WAAS enabled?!!?!?!?! Anyone know if there’s a certain setup needed in the GPS setup. I tried EVERYTHING, and even called Lowrence, who told me this is normal??!!! Excuse me, I’m no expert, but I know GPS’ with WAAS signal being received should be accurate to + – 20 feet? no? PLEASE HELP!!!!!!! Starting to dislike this unit!
