There are two reasons you would want to plug your iPod into your Toyota Corolla. You either want to charge your iPod while driving or play your iPod’s music through your car’s speakers. Perhaps you would like to do both at the same time.
Corollas With an Auxiliary Audio Jack
Step 1 If your Corolla has an auxiliary audio jack, which new models have, purchase a unit that has both the 12V auxiliary power cord and auxiliary audio cord. These are sold at many electronics stores. Some examples are the Monster iCarCharger AUX 1000 and the Kensington LiquidAUX.
Step 2 Plug the 12V auxiliary power cord into your 12V auxiliary power jack, sometimes called the cigarette lighter, in the Toyota Corolla.
Step 3 Plug the auxiliary audio cord into the auxiliary audio jack in the Corolla.
Step 4 Plug your iPod into the iPod connection on the device.
