Just bought one of these and noticed the tidal information screen - so useful for the yanks! Anyone know if there is any way to upload these with UK tidal data?
I also have a 76 although the MAP one. At this stage there is no way to alter the tide tables. I asked their support directly by email but haven't received a reply yet although that was months ago so aren't expecting one either!!
They are about to release their Blue Charts on CD which you can use for maps if your is a MAP76.
You should upload the latest ROM from the Garmin website as it has a number of bug fixes.
