So, I dusted off my Infuse 4G Car Dock and voila! The S3 fits! Height is perfect but the S3 is a tad narrower than the Infuse so some very minor side to side alignment prior to sliding the connector in is required. Other than that it fits like it was made for it! Enjoy! 

Update:
Audio output works as well!

This is interesting because there are a TON of vehicle mounts in different configurations beside the usual suction cup or air vent mounts. Makes it that much better if you don't mind it not being universal for each car.
