MULTIMEDIA SOFTWARE FILE DOWNLOAD

The multimedia software update file may be downloaded directly from this Service Bulletin by
clicking on the file name in the table above.


Multiple files can NOT be on the same USB flash drive; if there are two files on the USB flash
drive beginning with “rb_update” the software installation will NOT begin.



Storage capacity: 4.0 – 32 GB.
