Sony is revamping its Xplod line of car stereo units that will work with iPods. The iPod-aware models are the GT630UI, GT430IP, GT330 and GT130, and each features a USB connection that transfers data and charges the iPod.

These are the first models of their kind that feature scan technology known as “ZAPPIN”, which will do what auto-scanning does for radios, but for your digital content. So, using it will play samples of each track in a given piece of the listener’s library so you get a taste of songs, rather than text descriptions. If you want GT630UI you’ll have to pay $160, while the GT430IP and GT330 will cost $130 and $100, when they’re released in September.
