You can access current firmware info onscreen through the MFD menu. Current version is 5.16 released in 2012. If your chart is the original 2007, you should purchase new charts if you do any cruising outside your area. Lots have changed in 10 years!
Thanks Paul,Jack,
The upgrade is relatively straightforward and Raymarine's website will walk you through the process...
The file extension should be .zip not DOB. Check the file you downloaded for .zip at the end. Also check if you have a win zip installed.Was able to purchase a new Sandisk 128MB compact flash card on EBay. Downloaded the C80 firmware update to desktop on my PC. The Ray instructions are to open & unzip the files on the PC prior to transfering the unzipped files to the Sandisk card. When attempting to unzip the files, it won't open. I get a message that windows 7 can't open the files with a DOB extension. Anyone experience this? If so, what was the solution? I attempted on two different PCs.
Same with iphone 6. Amen to thatI asked RM on their forum about upgrading. You can go there and read it. Very wishy-washy. If your system works and you can upgrde charts, dont bother. I kept upgrading my iphone 4..now it runs slow, runs out of battery and is a piece of crap. It worked fine before for what i want to do with it. Its called planned obsolesence.
Good stuff on being able to keep both cards just in case. I think if you do it online, you end up re-formatting your old card with the Update Card, but if you go into the store you get a new one so you'll get to keep the old one and not overwrite it.Seems that Navionics has an update card that is available for about half the cost of a new card software kit. You have to have an OLD Navionics card in order to update. The update package comes with a NEW card; however, you have to have an OLD card to insert in your computer's card reader or usb card reader adaptor to register the Old card before you can open the NEW card and select the territory that you wish to navigate. Once your selections are completed and saved, you actually use the NEW card in your chart plotter. You can save your OLD card that is not overwritten for back up. The cost of the update card is approximately $100. and includes updates for one year. IF you search You Tube for "Navionics Update Card", there are a few videos about the update process. Hope this chart update works as seamlessly as described.
