great news.. while watching a car tech guy, on cnet got me to do a search on streaming audio for the car 4G telematics is what the radio device is called.. a related article here http://www.extremetech.com/extreme/174287-ces-2014-4g-cars-usher-in-the-era-of-the-seriously-connected-automobile
Nice article, but it highlights the issue already mentioned:
"It will be interesting to see how Audi prices the data package. When Audi embedded 3G telematics, it offered unlimited data for $30 a month, an exceptional deal . The challenge for automakers as for wireless phone companies is they really want to offer unlimited data for a reasonable price for everyone — everyone but the 5% who use far more data than the mainstream user...
If you’re an AT&T customer, GM says you can treat the car as an additional device, or buy a separate data package. If you don’t have AT&T, you’ll need to buy the data package."
In other words, having 3G or 4G in your car means
another data plan, on top of your home broadband and/or smartphone data plan. Or, if you're AT&T, you can have it treated as another device...which may work if a) you have enough devices available to add to your plan without an additional monthly upcharge, and b) you're satisfied with AT&T's QoS and their coverage (not sure about the former, but Verizon seems to hammer the latter a lot in their commercials).
In other words...there's no equivalent to the stand-alone GPS that, for a single one-time charge, lets you stream music while in the car without having to rely on a data plan package. And it doesn't look like they have any plans to make one available as a built-in option either.
