BooSnap. Thanks for your extensive and very clear explanation of what you want to achieve. However, this has nothing to do with our iBOLT dock. Instead it is to 100% an issue with Samsung and they way they designed their firmware. Motorola considered a car-dock an integral part of the end user experience when driving. They assumed that if you are using their dock and running a 3.5 cord to the car-stereo without an active Bluetooth device paired, you probably want to use the phone as a hands-free speaker phone (very logical!). To facilitate this Motorola embeds a software solution that routes the sound from the phone calls to the car-speakers, just as the aux-out music, and on top of that they also integrates a DSP (Digital Signal Processor) into the phone that activates during a phone call (when in Dock) for the purpose of suppressing back ground sound and minimizing echo/feedback. This essentially turns the Motorola phone into a real, fully functional hands-free unit. Samsung on the other hand elected to design their software so that aux-out sound (all sound from apps, including the ring signal for incoming phone as this is generated from an app technically) goes through either the aux-out 3.5 jack OR through the microUSB if the right cable is connected to it (like an iBOLT.co or OEM dock). However, the sound from a phone call can never come out through the aux-out connection. Samsung have assumed that a Bluetooth hands-free solution will be connected to the phone unless the user is holding the phone to the ear and talking. Therefore the applications type "sound re-direct" do not really work, even if they can technically "force" the sound from the phone call to go through the 3.5 mm jack. The reason is that there is no DSP software to minimize background noise or echo cancellation (ever quality Bluetooth solution has one!) and since the microphone sensitivity is not resetting itself for a "hands-free" mode (it doesn't exist), the person speaking to you while driving will always say that you sound like you are in a wind tunnel. I hope this long and winding explanation makes sense? We've had 100's of people asking about this, from many different countries. Motorola makes a terrific solution for using the car-dock as a quality hands-free device but Samsung (and HTC) did not, it's really that simple. Believe me, I wish that our Dock could replace the hands-free unit as well, that would increase sales tremendously. Summary: For now, unfortunately a Bluetooth hands-free solution must be used unless you want to pick up the phone from the Dock every time it rings!
