I just need to share what I use in my '46. Like many people do now adays, i use an iPhone and have most of my music an the ability to listen to my favorite radio stations. I purchased a Bose wireless Bluetooth rechargeable speaker that just so happens to fit perfectly in my glovebox! It sounds as good as or better than most built in systems and the best is, when it is not in the truck, it is sitting on my tool box in the garage!
