Older 73sv Software Update

Yes, your unit has QD capabilities. Also know that you can directly record QD contours to your mapping card.

Regarding mapping, the memory limitation applies to updating the internal, built-in LakeVu map. If you tried to do this, then yes, since the 2017 internal mapping update is so large, it would not actually update the built-in map, but read it from the card.

But, based on your description, you actually have the accessory LakeVu HD mapping card. With all accessory cards, you must leave these cards in the unit to read the accessory card mapping. Just keep running the accessory LakeVu card and not worry about the internal, built-in mapping version.

One more question: Can I still update the unit to software version 4.10?

Thanks Todd.
