Those folks at Griffin Technology never sleep. This week, they announced the pending availability of the iTrip Auto Universal. Why "universal?" Because it will work with any portable music player that has a 3.5mm audio out port, and doesn't require a dock connector. Once you've connected the device to your vehicle's 12 volt accessory outlet (remember when we could just say "cigarette lighter?") on one end and your iPod's 3.5mm headphone port on the the other, you're set to select a free FM frequency and enjoy your own music. Sounds good to me.
No pricing or pending shipping date information was available as of this post.
