I actually *like* the factory antenna. It pulls in the FM station I listen to baseball and hockey. What I didn’t like that it was a silver color that clashed with my black Rubi. Another plus of the OEM antenna is that it is the highest point on my vehicle, and thus serves as an early warning...
Do you have a phone cable plugged into a USB port? I’ve seen that error in my Rubicon when the Jeep decides it doesn’t like my cable (which works fine elsewhere). Try unplugging any cables you have
