I'm wondering if anyone knows of such a thing as a car stereo bluetooth adapter? Basically, I'm happy with my stock stereo system in my car, but it doesn't have bluetooth and I'm sick of having to plug in the cord to my Droid every time I get in my car to go somewhere. Does anyone know if there's something that will plug into the AUX jack on the front of my stereo that is a bluetooth adapter to which my Droid's bluetooth could connect to, effectively letting me play bluetooth through my car stereo? I've been looking on amazon.com and searching these forums for something like this, but to no avail. Short of replacing the entire head unit (not a terrible idea, mind you), I've found no real options for wireless media playback in my car via my Droid. Thanks.
