Lake master compatibility question

[twinfree10]

I have an old bird 598 ci on this boat I just bought and in need for a lake master card for Texas . I have found a good deal on a card but it say it's ipilot compatible ,obviously mine is not but I just need to see contour lines at the momemt. Will this card work in my unit? (As far as just to show contour lines)

More than likely although the processor is quite slow on that old of a unit -but I can't guarantee it to be positive.

You would need the latest software update for sure - and to be safe, you should call HB C/S Monday and verify it will work.

The v7.300 software description states it add support for AutoChart PC and ZLC, which is user generated mapping based off LM technology, so if it's necessary to make a decision right away I would say it'll work OK.
