A:AnswerYes this radio will fit in your car. We recommend you have Best Buy professionally installed for the best fit and a integrated look and sound. To get the NASCAR channel, you'll need to get the Platinum Plan subscription which will allow you to listen on both this radio and via the SXM app on your phone or connected devices.

A:AnswerNot in the sense that you can take it anywhere but it is portable from one car to another. If it is fully installed in your first vehicle you can add an additional vehicle kit to move it to another car.

A:AnswerThe installation in a heavy truck is very similar to the installation in an automobile. You may need to get a truck sat radio antenna or mirror bracket for the supplied antenna that comes with the Onyx EZR in order to get the best reception. Check out our Road Dog Trucking channel dedicated to professional drivers on channel 147. For Geek Squad installation, I'd recommend calling the store directly to see if they can service your Peterbilt.
