Now that my Carry is road legal the AM radio was not cutting it . The Fire and Brimstone ,crazy political talk, and non English stations with that fine AM hiss and buzz just sucked . hitting the on/off knob with my knee all the time didn't help ether . I just wanted something easy to install and low cost . I found a Pyle brand mech less AM/FM with a USB/3.5/SD card slot and built in speakers and a aux out on the back . For under $25 to my door it's just fine For a cab that's the size of a file cabinet it will do for now . While working on in the dash I also added a 12v power plug/lighter port . The wires were already there right behind dash just needed to drill the hole and plug it in .
