How do you update a Garmin 440s-Chart plotter-fish finder

[Big Boat Bay Buster]

The software and charts are dated 2008.Its overdue for an update. I downloaded the latest update from the web sight and ran the program to install it on a Sandisk card. When I put the card in the 440s, nothing happens. There is no option in the menu to update. Any suggestions?

Put SD card in unit before you turn the unit on. Should update automatically

Apparently, this chart plotter can't read an SD card greater than 2 Gigs. I was using a 4 gig card. I also found out the update does NOT include new maps....that you have to PAY for!! I guess it doesn't matter that I paid nearly $500 for a baby chart plotter.

The update is for the FIRMWARE in the plotter.
The charts are usually updated continuously.
An unlimited one year subscription typically costs about $100.
As the charts don't change all that much over the short term; I only get a new subscription every 3-4 years.
If you have 7 year old maps, it may be time to bite the bullet!

I agree
