How to install an aux chord jax into my Toyota Avalon?

I really hate listening to the radio and i recently bought a friend's Toyota Avalon its a nice car but unfortunately it doesn't have an Aux Jax where i can plug in my aux chord and listen to music from my iphone. Is it possible i can have something installed so i can make that possible?

There are several answers.

A) an "FM Modulator". I bought this for my wife's car a few years ago. Unfortunately, the antenna is outside the steel box of your car and the transmitter is inside. These also take a considerable amount of power.

B) Some car radios have an Aux Input on the back. My 2003 radio did, and I had them run a wire out to where I could use it. But a factory original radio won't.

C) Fake cassette. If the car has a tape deck, there are "tape cartridges" that you plug into it with an earphone cord dangling, and they will present a magnetic signal to the playback heads. I've used these with my ghetto blaster a few times, and the audio quality is good. Assuming that your car is old enough to have a tape player.

D) replace the radio. I just replaced the radio in my car for exactly that reason. The new radio allows streaming Bluetooth, so I don't even have to plug a wire in. My (non-apple) phone goes to pause when I get out of the car, and so long as I get back to the car in a half hour or so (one of them stops looking for the other if I'm away too long), the song resumes from where it left off when i turn the car back on. I don't know if an iPhone supports streaming Bluetooth for music, but your phone costs four times what mine did, so it MUST.
