If you are old-school and want a DVD mailed to your house, you can opt to buy the subscription using RVN5115AN (current as of 13 Aug 2017) at $399.00. It doesn't make sense to me to pay that much just to have a hard copy on DVD. It is the same CPS as the download.
As Crazyboy points out, you'll need to take the wideband course. It a silly little video that Motorola sets up via an online course. Once you complete the course (a few minutes), then the Motorola will have a copy of the certificate and they will allow you to search and add the wideband EID to your cart. They are free.
