Thanks for all the suggestions. I too am a former Droid Bionic person. What I liked about my previous car mount is that it also had the cable that connected it to a USB port that both went to my cigarette lighter (charge) and the audio in jack to my stereo (for music). Do any of the above options have that?
I had thought if I got a new mount, and use the existing cables from my Droid Bionic mount, that might work. However, it did not. When I tried taking my the microUSB from from my Droid Bionic car mount and putting it into the Droid Maxx, with the other end hooked eventually to the cigarette lighter, it didn't recognize it.
