Recommendation on mapping chip for Lowrance unit

[BassPastor]

Hello! 
 

My new (to me) boat has a pair of Lowrance HDS9 touches (not LIVE). Was looking for recommendations on what mapping card is best. The guy I boat it from was running Navionics Hotmaps, should I stick with that one or try something else? Any tips/experience would be appreciated! 
 

I pretty much fish exclusively in the lower Midwest.

That is probably as good as you will find.

Lowrance doesnt have many options besides Navionics.  They are pretty good in the Ozarks.
