Navionics and C-map sonar recording

[wicked walleye]

I purchased a Lowrance elite 9 ti that came with a C-map card and a Navionics+ card.  My question is when recording Sonar.  Can I use any SD card and then upload the info to both Navionics and C-Map?  Or do I have to have my Navionics+ card inserted into my Lowrance  to record sonar for Navionics and my C-map card inserted while recording to update to C-Map?

I guess this explains why there is hardly any "shared" sonar on lake erie.  East of Cleveland anyway.

One thing I noticed last night.  I loaded lake erie and lake Ontario onto the navionics card. I checked the boxes for "nautical charts", "Sonar Charts" and "Community edits". I then installed it in the Lowrance. I chose the option to read "Navionics" on the finder and turned on the "Sonar Charts". I want to see the 1' contour lines. I noticed that I only get the 1' contour lines if I zoom WAY in. If I zoom out to where I'd like to be the contour lines disappear and go back to a view that is like you turned off "Sonar Charts". I'd like to be able to zoom out as far as I want and still see the 1' contour lines.

You won't be able; sonarcart are really meant for fishing over specific structures and to navigate you use nautical chart

Yes, you need a Navionics card to be able to use sonarchart Live and for the c-map you need a blank card in youre unit.

So when I zoom out the contour lines are supposed to disappear?  I'd like to see a larger view so I can see where different small humps and pockets are without having to scroll all over the place.

The sonarchart lines may disappear at a certain point. Witch unit are you using? On mine the sonarchart disappear at .5mi when I zoom out

I have a Lowrance Elite 9 Ti

I guess that kind of makes sense.  At some point 1' contour lines would basically make the lake look like a black dot if you zoomed out far enough.  I wish I could make that setting myself though.  I think they disappear far too early.

.5 mi is quite farr: .5 view from the sky, it's like lloking at the lake at 2400ft.
