Wireless FM modulators

Wireless FM modulators make it even easier to listen to your iPod, allowing you to make connections without removing your receiver or running extra wires. The trade-off, however, is in sound quality. While wireless modulators are convenient, they are susceptible at times to outside interference and static. Installation is easy — just connect the modulator to your source and plug in its cigarette lighter power adapter. Some iPod accessories even combine a wireless FM modulator, a power adapter, and a mount for your iPod.

Cassette adapters

While they're not as common as they once were, wired cassette adapters are still a convenient way to connect your iPod to a cassette-based audio system. In fact, it's a great way to connect an iPod to a rented or leased car, since you don't need to remove the receiver or disturb the installation in any way. A cassette adapter, however, is a less than perfect solution for a permanent installation because it doesn't provide power for your source, won't sound as clear as a direct-wired connection, and clutters your dash with unsightly wires.

With that in mind, connecting a cassette adapter is a relatively simple installation. The cassette unit loads into your receiver and trails a cord with a 1/8" mini-jack plug on the end. Just connect it to your iPod, plug it into the adapter, power it up, and go. Once again, though, we suggest investing in a cigarette lighter power adapter to keep your iPod charged up while you're on the road.
