I have an IEFIS discovery . I sent it down to the repair center in the US for an unrelated problem. When I got the unit back after they updated all the map data .I could not get the GPS to find itself . It said it was in California. The antenna is connected. It finally found itself once. I think the problem is they did not install the Canada data base . If the GPS locks in I was only seeing US airports. Any thoughts on how to fix the problem.
