I would like to integrate my phone (Motorola DROID) and my car. I would like to be able to: Listen to MP3's stored on my phone over the car speakers. Listen to the SiriusXM app on my phone over the car speakers. Listen to voice navigation on my phone over the car speakers. Maybe listen to phone calls over the car speakers as well. What is the best way to integrate the phone with the car stereo? Can I do all of the above with and FM transmitter, or via BlueTooth, or a wired USB connection? Is one of the methods superior for sound quality? I've got a 2004 Jeep Liberty (stupid Chrysler 1.5 DIN slot) with a Pioneer AVIC-N3 in-dash navigation installed, but I'm not that fond of it. The AVIC has navigation and SiriusXM, but I use my phone for for both most of the time now. I could eliminate the AVIC if my phone and car become one with each other. I'm completely out of touch on car stereo technology. I was thinking about replacing the stereo and was wondering if there was a unit that would make this integration easier. All suggestions are appreciated. Thanks.
