At Macworld, Dension were showing an updated connection product for the current generation iPods. This new cable/cradle uses only the bottom connection, making the install a lot cleaner. You just drop the iPod into its car cradle and you're done. I don't know if it's up on their site yet nor when the updated product will be released.

I did find out that their product specifically links between the iPod and a SONY changer interface only. To adapt to other head unit makes and models (including OEM variants) they use an additional module from another company (that converts SONY to XYZ). That's why you may find support for one OEM unit but not another on their website right now.
