This is the first Samsung phone for me after multiple Moto models, most recently a RAZR. When it comes to Samsung or aftermarket accessories, it seems they are slow to catch up. I used to enjoy the Moto car dock with audio output and charging connections both via the mini USB connection. Is the only audio output available on the S5 the headphone jack ? Love the S5, but the audio/charging convenience is sorely missed. Are any charge/audio output splitter cables available ?
