Harman Kardon Drive + Play
There are plenty of cable kits out there that let you connect your Apple iPod to your car stereo system, but you still have to fumble with the iPod to select songs and playlists, a somewhat dangerous task while navigating through traffic. Harman Kardon's Drive + Play ($199.95), however, gives you the freedom to take full advantage of your iPod's user interface without risking life and limb.
The Drive + Play consists of three main components done up in a dark gray metallic finish: a 2.5-inch (diagonal), five-line monochrome display, a small rotary control knob, and a 5-by-2.5-by-1-inch electronics box (the brain) that connects everything together. The display and control knob assembly come with mounting hardware for permanent installation on your vehicle's dashboard or center console, and the electronics enclosure can be mounted under a seat or the dashboard or in a glove compartment. Harman Kardon recommends having the Drive + Play installed by professionals, and we agree, since there are lots of wires to run, and you'll need to drill holes to mount the components. However, if you have previous experience with car stereo installations, the written instructions do a good job of walking you through the entire wiring and installation process. Included in the box is a 12-volt cigarette adapter, a 12-volt wiring harness for connecting directly to the vehicle's electrical system, a cable for connecting the iPod to the brain, and various cable ties to keep everything neat and tidy. You also get a line-out stereo cable for plugging directly into your existing CD/radio unit.
The Harman Kardon Drive + Play can be connected to your car stereo one of three ways. The easiest option is to use the 12-volt adapter to bring power to the unit and select the wireless FM method of transmission. The brain has a built-in FM transmitter that will tune in to one of five predetermined frequencies to transmit iPod audio through the car radio. However, this method provides the least optimal sound quality and is subject to outside interference. You can also use a wired FM hookup, which produces better sound but requires a special wiring harness, which is not included in the package. The ideal connection involves wiring the unit to your vehicle's auxiliary input jack, but if you don't have an auxiliary jack on the front of your radio, you'll have to partially remove the radio to make the connection from the rear of the unit--you see what we mean about getting professional help.
