I replaced the sickly stock Ford radio with a Kenwood from Crutchfield with blue tooth, usb inputs, external mic for phone calls, CD player , AUX input etc..etc.. We always play Holiday Road when heading out, and i always crank it up. It is fun to see the folks that remember the Chevy Chase movie smile when they hear that playing from the RV. But otherwise, during the long drives, we will listen to an audio book. We enjoy all kinds of music from pop to oldies. I used to do DJ work when i was younger and built up quite a collection of music that is now on flash drives.
