FM radio receivers for the car.
Never could find a radio station that would work. When you did, it only worked for about 1/4 mile down the road and then had to find another station.
You were supposed to have an antenna.
If your car is old enough to have a tape deck, they have cassettes that connect via Bluetooth. Just about perfect sound quality since there is no interference.
I changed cars in January and the car I previously drove, an 05, Jetta had a tape deck. I bought this to connect my phone. Surprised that it handled calls as well.
I remember when those things first came out and used a headphone jack so you could plug in your CD player. (those were the days…)
I was actually kinda pissed when I had to switch to a car with a CD player and couldn’t use it anymore.
Yeah those worked way better than the fm transmitters. Only problem was my car introduced a humming sound into the signal that got worse with speed lol.
It’s probably interference from your engine’s ignition system. A better quality setup might have built in protection from that.
Where do you live? I don’t listen to the radio anymore but when I did, I could get my favorite station 50 miles away no problem.
It’s not the radio that didn’t work. These were fm transmitter/receivers you used to play mp3 players/cd players back in the day when vehicles didn’t use aux cables. It sent the signal over short range fm signal to your radio.
The alternative was the cassette adapter, but some vehicles had swapped to cd
