I recently purchased the Lake Insight Pro V16 card. I have 2 HDS Gen2 units LSS2. Units are linked. Waypoints marked on either unit show on both. When I put the map card in the console unit, the higher definition display only shows on that unit, not on the front unit.

Am I doing something wrong? How do I get the system to share the info on the card? Surely I don't need a card in each unit. The existing waypoint, prior to inserting the card, still show on both units. The package had no instructions. Does the info on the card download onto the unit once it is inserted?

Help!!
