Navigation software recommendation for 898c si

Southbound

What is the best navigation/ fishing software? with the navionics is the paltuim +worth the money? I fish 95% inshore but would love a software that has lakes and coastal area!

Thanks for the help

I use the Platinum + and have been very happy with it. I went the route of buying an "offshore" and a lakes chart. Expensive but it works for me.
