Honestly, I may be tempted to buy this dock... no... really...
The only caveat is, I wouldn't use it for the GPS functionality. The fact that it has a bluetooth speakerphone setup (my Jeep doesn't have such a feature) is appealing.
Also, I have yet to find a nice mount for my iphone that also charges it while providing an auxiliary output (My jeep DOES have an AUX in jack), which doesn't rely on the 12v cigarette lighter port for support.
Finally, I want a mount that is not bulkie. This one conforms nicely to the phone, and doesn't require you to plug in cables. Just dock and go (nice and clean).
The only concerning thing is compatibility with future iPhone models. Will it still work when I upgrade to the next model???
Like I said, I like what this dock brings to the table. I wouldn't necessarily use it for a navigation application, but I think that aside, it's a great looking product (and PLEASE tell me if there's a dock that comes close to meeting my "demands")
