From an Avalon to a Yaris, connecting your iPod to your Toyota can be very difficult. There is a multitude of options that can be overwhelming. The three main types of Toyota iPod adapters are wireless FM transmitters, direct audio inputs, and wired FM modulators.

Wireless FM transmitters are the simplest type of Toyota iPod adapter. These devices usually plug into the cigarette lighter socket. Once you connect your iPod, the adapter will transmit the audio via a wireless FM signal to your factory Toyota stereo. Also, if you get an iPod-specific FM transmitter, it will charge your iPod. So, like most people, you’re thinking easy enough, I’ll just buy one of these transmitters, plug it into my cigarette lighter, and my problem is solved. In most cases, it’s not that easy. Most people find FM transmitters pretty awful. No matter what happens, you will have some kind of static in the background. Also, the audio will in and out according to the transmit power of the radio stations in your area. After a month or so of owning one, you’ll probably be looking for a better type of iPod adapter.

If you’re lucky enough to have a Toyota that has provisions for it, a direct audio input is your best bet. A direct audio input uses the CD changer port on the back of the Toyota radio. This port together with the adapter allows for the best possible sound quality. Fortunately, most Toyotas from 1998 to present have this port. The best adapters will plug into the bottom of your iPod, allowing you to charge your iPod and also allow your factory Toyota radio to control the iPod. This adapter allows you to fully integrate your iPod into your factory Toyota sound system.

So what if your Toyota doesn’t have the provisions for a direct audio input? Well, your best bet is going to be a wired FM modulator. A wired FM modulator is similar to a wireless FM transmitter, but better. A wired FM modulator interrupts your Toyota’s factory antenna cable and sends iPod audio directly to the FM tuner through the radio’s antenna port. Since the FM modulator interrupts the antenna, unlike an FM transmitter, no matter how powerful nearby radio stations are broadcasting, your iPod’s audio won’t drift or have static. This adapter is universal and will work on any stereo. The only drawback this adapter has is degraded sound quality. Since the sound quality of the FM tuner is not as high as that of a CD, you will lose some of the sound quality of your iPod.

Connecting an iPod to a Toyota can be a bit tricky and confusing. Just remember that your best bet is a direct audio input. If your Toyota radio does not have provisions for a direct audio input, a wired FM modulator is the best option. As a last resort, you can use a wireless FM transmitter, but I don’t recommend it.
