The audio books are on CD so need to copy them to a flash drive or some other method. If using the flash drive method, I thought the CDs could be download onto my PC, converted to MP3 format and copied to a flash drive. But I have not been able to find a procedure that does that. Maybe someone knows of another successful plan, possibly using Bluetooth, or the iPhone, or ??? Listening to a book on a long drive is very relaxing, and I plan to make several long drives.
