Hi, I have an Icon HD built in 2011. It is a model before "Net ready" and AI. Firmware version 2.02. In the "About Icon HD" section is a line "Upgraded". I have been told by other divers that I should update its firmware. On the Mares website "Downloads" I found V2.5. The picture suggests, it is for a AI model - or is it just a generic, not a model specific picture? I made a download, but my Mac says, there is no application set to open it. My question - should I update my computer, is this the correct FW version and how to do that?
