Can’t pick a song while connected to car

Hello

1. The cheapest option it's auxiliary audio cable you can pick one of these up at any electronics retailer or ebay aux cable
2. You can buy one car cassette adapters, it works inpretty much the same way you plug aux cable into your iPod and plug the other end right into your car stereo cassette ebay car cassette adapters
3. Another way for getting your iPod integrated into your car stereo system is to use an FM transmitter. You plug FM transmitter into your iPod and this end goes into your cigarette lighter, it has a radio transmitter like a tiny little radio station and you tune that in your car stereo ebay FM Transmitter
