New Ant, TER Strength but no SAT strength

I have had a Sportster 5 for over a year and now I am experiencing signal loss and the Aquiring Signal and Antenna Not Detected error messages in my car. I replaced the antenna, the docking station, and have no problems using the radio at home. What else is there that I need to replace or check?


The only thing strange that I have noticed is that the TER strength is 50% to 100%, but the SAT strength in the car is 0%. Is is possible that the "SAT detector thingamajig" in the radio has gone bad, if there is such a thing?
