I found this same 5.12GB 2016 RNS-E release elsewhere, and I'm not sure it can ever work. It is not delivered as an ISO file, but as a directory structure. I don't think an RNS-E system can boot it like that. I burned it as a UDF DVD-ROM using the same drive and disc brand that I used to successfully burn multiple RNS-E 2013/2014 North America discs, and it wasn't recognized by my nav system.
Has anyone ever gotten this to actually work? What settings did they use for the burn? Many settings are taken care of within an ISO file, whereas this file system release leaves a lot of unknowns.
