zalienz Posted August 6, 2020 Share Posted August 6, 2020 So one day i noticed on my Sync 3 system, the GPS logo had the red circle and a slash through it, indicating the GPS signal was lost. I recently updated the maps and wondered if it was a software glitch, as it was working correctly, until a few days ago. No glitch, suddenly the car is lost on the map and it's all over the place, no where near where I was at. A look at the wiring diagram and it shows the GPS antenna and satellite radio antenna are the same and there is a splitter for the two. I tried Sirius Radio, and bammo it's not working either. I decided to buy a new antenna, it was only $30, and will work on it this weekend after I pull the headliner. Wish me luck, I'll post the results.

zalienz Posted August 9, 2020 Author Share Posted August 9, 2020 Well, I got lucky, the GPS antenna was bad. I used Forscan to pull DTC's, and it displayed B1A89:13 - Satellite Antenna - Circuit Open. I purchased the antenna from Ford Parts online, and a local dealer had it in stock and I received it in 2 days. Dealers only stock fast moving parts, so my guess was fortunate. Navigation and Sirius Radio is now functioning correctly, only took about 30 minutes to drop the left side of the headliner and swap it out. I hope this helps others in this situation. Peace out.
