Most people do not have internet in their car, however there are ways to get it without
spending a million bucks though you won't have the controls exactly. The basic way would be to use your smartphone with it's internet and plug it into your cars stereo system. You first need to identify what kind of input/output your car stereo system has. Then, as well as your phone.
You can visit your local Radio Shacks or Best Buy. You can also use Motorola devices as well as Bluetooth to do some hands free internet surfing. If your car lacks an input, you can use a cassete adapter with a 3.5mm jack. Good luck!
