It tries to make your head unit "smart" by displaying some information from select services on your head unit. In reality it's mostly useless. You need to have the entune app running on your phone which contains the available services. Pandora may be the only useful service unless you think looking at stock prices or attempting to buy movie tickets on a slow laggy interface is fun. The whole thing is rather buggy and slow and I end up playing pandora natively on my phone anyway.
Google maps is not supported.
