Question: has anyone here been able to play music via USB connection in their car?? If so, then list your car brand and model. How did you do it? Are the songs all MP3? from Itunes? Are the songs in any particular folder on the microSD card?? Me: 2010 Prius NAVI...the car audio can only read 3 songs out of many (all from Itunes). I do have 2 songs from Amazon MP3, but they are not read either. The same 3 songs over and over again. My phone is in "mass storage" mode. Thanks in advance.
