Hi guys, I am from iBOLT so I can bring some clarity to this issue. On S3, S4 & Note 2 &3 Samsung featured "analogue audio out" through the microUSB connector. Of course you had to have the right cable that put the phone into "dock mode" which triggered this functionality. However, in their infinite wisdom Samsung decided to remove this permanently on Galaxy S5, Note 4 & future handsets. This was unbelievable as almost all no car between 2004-2011 features A2DP Bluetooth chip set that allows for sound from Apps to be transmitted via Bluetooth, although many have Bluetooth hands-free built in and the aux-in port. Even some newer cars do not include the A2DP, only in the "navigation/premium package" that dealers. However, we have finally worked with vendors to come up with a great solution.
Our solution is the "Bluetooth streamer charger", see attached pic and link below. This is a 2.1 Amp USB car charger (a must on the S5 & Notes) with built-in Bluetooth receiver and a curly cord with aux-out. Simply plug the charger into the 12 Volt outlet and the aux curly cable into your aux-in port. Pair with your Android phone. Select "media only" (assuming you have another hands-free solution for phone calls) and from this point your App sounds (GPS, Music etc) the Bluetooth charger will automatically connect with your phone when you turn the ignition on and it will stream your music etc into the car speakers. For charging, just plug a standard charging cable into the car charger.
This concept is a great solution since the Bluetooth receiver is built-into the car charger it never needs separate charging. If you plug it into a power outlet that starts and stops with ignition (most but not all does this) it will also connect every time you step into the car.
We just activated a "Charging kit" today on Amazon.
