So basically if I am understanding correctly Hot Maps premium was just nautical maps only with no sonar maps at all and of course limited to the East in the version I have. And now with Navionics + I will have the same maps (nautical) that I had with Hot maps only for the entire USA and additionally if I choose to I can download sonar maps which I never had in the first place with Hot maps.

Yes. The only other card to have the SonarChart layer is Hotmaps Platinum which only works in certain units, check compatabilty guide on the website. HDS units can use Platinum

I think I only have one more question. Once you download a sonar map for a lake can you switch between the nautical and sonar maps when viewing in the Lowrence or does the sonar map replace the nautical one?

Yes you will see a setting or choice when you install and select between Navionics - Navionics Fish n Chip aka SonarChart - and Lowrance (which will be the base map unless you by a Lowrance Lake Insight card)

Thanks for you time and patience. When I was buying the Lowrance unit paying the extra for the Navionics to come with the unit was just a last moment impulse and I didn't even know about all the changes until after the fact. Since I have Navionics already and was happy with the product it seemed like a no-brainer.

Make sure you go to the Navionics Website and go tot he web app and preview the mapping

Make sure you select with the Fish n Chip or SonarChart setting on your sonar

Pretty much all mapping updates are done thru the SoanrChart layer

I would recommend doing a freshest data upload to your card monthly to get the newest data from Navionics.

i appreciate your help! Thank you!
