Lost the Tidal Charts on my Northstar Unit?

Well, Mahalo finally got launced last Friday to the CP Yaucht Club slips. On May 1st, opening day at Bayside pulled up to set up a spring line on their new slips so I'd be ready for the afternoon return.
Started out a bit choppy for a BBQ so we decided to tuck in to the cove at New Rochelle, water turned to glass and winds cut down by afternoon but....Buddy Larry the Frog was the first to break the ice into 52' waters, a bit too much shrinkage for my liking.
Earlier pushed the buttons that would show the graph with the tides on lt to have a reading "No Tides for May first", pulled out the chip and reinstalled, still no tide charts
Anyone have any ideas before I make the Northstar calls?

Our Northstar unit is just over ten years old, and I understand the tides charts don't go out that far, so we don't have them either............how old is your unit?

I believe my unit was from 2005 or 6 When I called Northstar they said I can update the chip from their website but I would like to buy a complete updated chart which probbably will include the tides
