All, I am with iBOLT. The HTC One S is the same Dock as the one for the X, that is correct. It works perfect but there's a 3-4 mm open space once inserted on the left side as the S is smaller then the X. The functionality is the same, it starts the car mode with the very good HTC car dock application but we are hearing that many are using CarHome Ultra as well since this app has more flexibility, although possible not as nice looking.
With regards to Aux-out it is correct that this Dock does not work like the iBOLT Galaxy S III Dock with integrated charging/aux-out from the microUSB cable. This is because there's no technical way of taking the aux out from the microUSB connection on the HTC platform. We wish it was since this feature has been incredibly popular on the S III. If your car-stereo features a 3.5 mm jack I would recommend the HTC Bluetooth dongle for Streaming Audio unless it can be done over the BT system.
Hope these comments helps...
