Navionic Sonar Charts on older (pre-evo) SIMRAD NSS MFD?

[PJHoffnet]

I have a pre-evo NSS 12 MFD/Chart plotter running the latest (V3 rev 4) software update.* Chart chip is the Platinum + 906P US Southeast - Bahamas.

When I use Navionics chart installer it has the daily updates for Charts, Sonar Charts and community edits.* I d/l them all onto the chip and can show the Navionic chart (obviously) and community edits on the MFD, but I can't find an option to show the sonar charts.* *Any other pre-evo NSSrs able to show the sonar chart?

I run Navionics on my phone and tablet (Android) as back up navigation sources so I can always check the sonar charts there - in fact, I typically keep the Navionics in sonar chart view.

​​​​​​​Thanks in advance.

Found it .... Fish & Chips mode (I always figured this was just some type of 'hot spots for fishing' kinda thing. To get there, Chart options => view ... operations manual didn't bother to say anything about that mode wte of 'The NSS supports Fish & Chips'
