It's "clear the shelves" time. i.e. I only want an AM radio and Ford makes me buy FM and satellite radio to get it. "Clear the shelves" for all the unwanted features.
Here is a great link to everything you need to know about automobile antennas...

Antennas are not that complicated...I remember just sticking some copper wire in when I was a kid (or some used a coat hanger). But, copper conducts better. The key is having the correct dipole length. If you are familiar with CB radios, extra long antennas are used and a SWR (standing wave...
The length of the antenna is determined by the wavelength of the signal being received. The FM signals are at a much higher frequency (shorter wavelength) than AM. Effective reception of AM requires a longer antenna. Stubby antennas will have little effect on FM reception. But, if not properly...
On Jeeps it's called a stinger bar and used to help prevent tip overs on steep declines. I installed one on my 2018 JKU and it looked cool but in Florida, I never got in the situation where the decline angle warranted a stinger. I think I'll wait a bit.
Maybe I misunderstood something? It said to pull the radio and install the adapter between an existing cable connection. (Some sort of inline (serial) programmer or wiring that establishes permanent state change for the device. I was hoping for an ODBII programmer.
I learned early on to be careful what photo I used for my wife in my i-Phone...when her photo filled the screen when she called me one day...everything is PG now.
I would be more cautious...people have died from CO in their car...especially during snowstorms, etc. If I can smell exhaust in the least...I'm shutting it down. Besides...if you are so sensitive to the heat, buy a portable A/C unit.
