Lighthouse II map faded to black.

In tracking down another problem on my a98, the Raymarine tech download the newest v17 software in hopes its would be software corrected.

All seemed fine for about 2 days, then the lines on the Heartland map began to blur, depth contours disappeared and the new map shifting into view was pure black. Eventually NO MAP at all.

I had to return to the Basic Map.

Do i need to purchase a new updated map? Is Lighthouse a subscriptions service?
