Michael, let me ask for some advice here. I received my CD and have loaded it onto my computer. How ever, when I connect the USB cable to the radio it displays the Boot Ver. and App Ver. Then it should ask me if I want to look for updates, but on my display after it shows the Boot Ver and App Ver, there is one blank line then it shows, "CPU SW Upgrade:" and the next line says "Waiting for USB." I am wondering if who ever sold this radio just found a USB cable with the proper fitting ends and included it, and the correct USB cable has a separate chip in it or something. I check my device manager and the radio shows up as a mass storage device, so I know the computer is reading that there is an SD card there, but the radio is not asking me to look for updates. Does that sound like I have the wrong USB cable and need to get the correct cable, or do you think I have a different problem? I am all ears oh wise one! And if you think it is a bad cable, could you give me the RSU# for the USB cable. As I do think my girls at the Radio Shack will know how to order it now. Thanks again for any help you can give.
