Suggestion, is get a Windows computer to do the update from, a friend or even the library if you do not have one. I would not put faith that RM has the Mac side of the software working. The current update is probably going to be the last and final as the RV units have been discontinued along with future support. They may have map updates for a fee, but no longer support updates.
That sovled the issue
dug out an old pc and it fixed in in a few min
That is what I like about Entegra IRV2. someone always has the answers
