The issue lies with lollipop. They changed the way they handle USB from UMS (USB Mass Storage) to MTP (Media Transfer Protocol). Basically, the only way to connect your phone to your car via USB, and have the ability to skip songs, and view song information in your car is to root your phone. You can then download an app in Google Play to choose how your phone handles USB connections. By picking UMS, this should then allow you to use your car in the same way as an iPhone doeswhen connected via USB.
