I relocated my shark fin antenna to my dash on my 2024. As far as I can tell it is used for AM/FM, cellular for the Uconnect system (updates, safety features, etc.) and phone, and WiFi hotspot.

I listen to FM HD radio and I didn't want to just remove the antenna. I also didn't want to lose OTA updates (the antenna also incorporates the cell antenna). Additionally if you just disconnect the antenna you will get an UConnect error message every time you start the truck.

I decided to relocate my antenna to my dash passenger side, at...
