LX Model, purchased day after thanksgiving.

Disappointed that it didn't come with floor mats but ordered some off of Amazon.

When I first set phone (iPhone 4s) up it seemed like it could do text messages but I didn't experiment. Over the weekend I upgraded my iPhone to ios8 and now while it does calls it won't even display the option to enable text messages. And I notice that when in Pandora or Podcasts, it won't let me switch stations/feeds, counter to what the manual says it should do.

What is the best smartphone to pair up with this 2015 Honda Fit LX?

Also, my model seems to be missing an antenna, I can see where it screws it and the manual indicates that it should have come with the car
