I have the droid x OEM dock and love it. In my van I can put plug in the 1/4 headphone jack a tape deck replay tape and hear my phone calls and music along with turn by turn using my vans speakers. My problem is my truck is a 2001 and doesn't have a audio input on the dash.I have CD only so how can I hear my music, phone calls and nav turn by turn? What do you guys use? It would be nice to be able to have built in mic for making calls but not needed.
