Replacing my entire GPS system would be undesirable, to say the least.

Any ideas would be appreciated.
From Google AI....

"Garmin Navionics+ and Garmin Navionics Vision+ chart cards are compatible with Garmin 7000 series chartplotters. These chart cards offer supplemental mapping and features when used with a chartplotter that already has built-in BlueChart g3 or LakeVü g3 mapping. The Garmin Navionics+ and Vision+ charts can be downloaded to the chartplotter using a card reader, and they will take priority over the built-in charts in overlapping areas, according to Garmin"

Not sure if this helps you or not but thought it was worth posting...
