The card that comes with the Elite4m is not as good as the stand-alone card.
It does show bottom contour/depths.....but not as good as the stand-alone card.
Every time I turn mine on, sofar, I have to go in and program it to "Navionics Coastal Canada".
Otherwise I get nothing on the screen except " Lowrance" setting...which is default.
The Lowrance map setting is good if you were fishing, say, Friday Harbor or Puget Sound......but north of the border there is nothing.
Probably there is a way to keep it on Canadian setting.......instead of having to do it every time......
But I haven't figured that out yet.
