Thanks, techgeek32. I essentially do the same thing that you do. But I always leave my bluetooth turned on on my phone and I also keep the stereo clip turned on in my car. I have a Subaru Outback and the aux port is deep in the center console. It's a pain to fish around in there to hit the button to turn on/off the stereo clip, so every time I get in my car I need to go into my phone's settings, bluetooth, and press the "HTC Car A100 V2.4B"
The process isn't terribly demanding or time consuming, but I was hoping the two devices would see each other and connect automatically just like the bluetooth phone system in my car does with my phone.
