Hi Jim. Yes, book courier supports audible books in format 4 only which is highest quality, lowest compression. Before you ask why this is, licensing and patent problems with lower format compression mean that format 4 is the only supported type. You will need to use the transfer tool to first authorise your Book Courier before sending books to it. Information about the workings of Audible file support can be obtained from the BC's user guide available in the support section or frequently asked questions on the BookCourier website at http://www.bookcourier.com. Should you require any further assistance, please let me know and I will be more than happy to help.
