Everybody wants all kinds of stuff but doesn't think they should pay for it.
Good luck with that.
In my opinion there is no real reason for why we should have to pay twice for data. The capabilities of the MMI system are far less than our phones which already have LTE, so if they made the MMI use our phones for apps and data it would instantly be far more capable and impressive. This is how it is done in the rest of the world.
None of it is essential to the operation of the car, thankfully. I don't see the advantage to a Google satellite map. At least traffic from Sirius in free for 4 years.
The only things we're missing out on is online destinations, weather, and fuel prices. But even the 2013 VW's have better weather since they use Sirius weather for doppler map overlays, movie info, gas info, and even sports scores via Sirius.
