The battery died on my wife’s 2012 Honda Pilot. Put a new battery in and needed the code for the radio, no problem there. The Navi system is search for gps satellite. Yes a went to a open field with no power lines or tall building. Sat with the motor running for over 10 minutes and the screen has the same message. I did the hold the 3 Navi system buttons to get into the diagnosis screen and found that either the ecu or the antenna is bad.
