Navionics Update Chip
The delivery and quality of the product were flawless. I'd like to add something to the instructions for activating the card that were sent via email. If you already have the older version of the Chart Installer software installed on your computer, the expected option for activating the update chip won't be there. After a lot of trial and error and unsuccessful searching online, I finally completely uninstalled my existing version of Chart Installer and then downloaded and installed the software again. And lo and behold, everything works as smoothly as described in the instructions.
Perhaps new customers should be made aware of this. And be warned, there's no going back, so look carefully, read the instructions, and decide what you really want.
In retrospect, everything is great!
