GP-1850 Navionics Card Replacement

[Creeksailor]

My 2003 Furuno GP-1850WDF has a Navionics 2003 Chesapeake Bay Card, Code US634XL X. Is there a Navionics card that includes the Chesapeake Bay region, is more up to date and will replace the card in my GP-1850?

Unfortunately Navionics stopped making these types of maps and cards in 2009 and C-map stopped around 2015. Any chart cards wanted for these older units would need to be found on the used marketplaces like ebay.
