JAVOedge's 3.5mm to 3.5mm Stereo Male to Male Retractable Cable ($15) is a simple black accessory that enables you to connect your iPod to the line-in ports found on some car stereos and most home stereos. The cable gives you several feet of length at its maximum, or under a foot at its minimum. Notably, the cable we received is not compatible with the recessed headphone port of the iPhone.
