Yes, the 2.5 adapter will work. I use the aux jack in my car with no problem. I wanted to be able to create a hands-free set up, so I bought a Seidio audio adapter with microphone (2.5 male to 3.5 female) and got a 1-ft 3.5 male-3.5 male cable to go into my radio aux jack.

The 6700 fits great in a cheap vent-mount holder designed for iPhones that I got at Best Buy, so I just have to pop the phone in and I'm good to go.

When I'm really bored and stuck in traffic, I'll sometimes even fire up Slingplayer, listen to TV in full stereo, and (very occasionally) glance at the picture.
