Damn you, Sony!
I bought a Sony head unit at a local retailer. Just a cheapy until I have the $$ for my double din and the custom fab work I want done. Model CDX-GT575UP... It clearly states that it has Android Music Playback support on the front of the box. I took this to mean that it had USB support for android devices, but I can't get the damned thing to connect to my phone. Looks like I'll have to shell out more $$ to get one that will work. I think I'll be going with Kenwood or Panasonic this time around...
