Recently, I took my car through the wringer and came out missing the antenna mast. After going back and finding it, it’s clearly broke and will not reconnect to the base. I’ve read several older discussions where shark fins were not a replacement option. What is the 2019 view on Shark Fins? My radio has Sat and AM/FM, no navigation. I’m skeptical to purchase one from eBay as it doesn’t match up the part number and supports NAV. Are the connectors different between my oem replacement, or will I have an extra connector dangling in the headliner for the NAV?
