We have the same problem with out 2019 F-350 (special ordered with Camper Package). Initially I reached out to Ford Corporate Customer Service regarding this design flaw with pathetic results. Then I attempted to resolve the issue via an independent stereo shop, then a Ford dealership (I also had a Ford dealership decline to even attempt to resolve the design flaw). Both shops went above and beyond;however they were ultimately unable to restore both satellite radio and GPS. So this is our current “solution.” The Sirius Satellite Radio Antenna Kit used by others in this thread mounted on the plastic cowling (passenger side at base of windshield) solves satellite radio issue. We purchased a Garmin RV 890 GPS for routing.
