So I got a new fish finder, LCX-17M. And I got a map chip for it, the Lowrance Fishing Hot Spots Elite http://www.lowrance.com/mapping/FHSelite/west.asp
Turns out the chip does not have a few of the lakes that I usually fish on it. I looked around an the Navionics maps do have some of the lakes I want, specifically Don Pedro and several other motherload lakes.
The question is, if I buy the Navionics chip, and I put it in the card slot at the same time as the FHS Elite chip, which one will display for lakes where this is coverage on both chips? Or will it work at all?
