Antenna issues

OK, I won't pretend to know much of anything about audio. Have a 2014 Tundra that was missing an antenna when I bought it from a dealer (3 hrs from me, not worth the drive back). At first, I just dealt with the lack of tunes unless I was practically on top of the station. Finally bought a replacement antenna, one that was supposedly like the original. No improvement. I can only assume that something isn't hooked up to where the antenna screwed in. Can someone please direct me to a YouTube video or give me some good instructions on what I should do next? Summer is almost here, laid off due to Covid, road trips are better with tunes! Thanks!

 

Is your stereo a factory installed unit or an aftermarket?
