The 2015.10 file format changed and cannot be applied to the RHB radio with the v50 software.
We would need a software update to work with the newer map file formats and I don't see that happening any time soon considering the age of the radios.
Yes, I'm quoting myself...
Another little tidbit of information to add from experience (and other threads) is that IF you have the v50 software version you CANNOT update the maps. It will fail no matter what you try.
You have to downgrade the software to either v43 (if you have the disk) or v33 (ISO image for disk is available from a lot of sources), update the maps, and then upgrade back to v50.
Sounds daunting, but it's actually quite easy, just time consuming.
