OK, thanks for the clarification. I had read you needed a Ilink compatible card but the way the HB website reads, it almost makes you believe Ilink works with the Contour XD, or you want to believe that it will work with the Contour XD mapping.
Contour XD does have contour lines for 3000 lakes ...but most likely not the lakes you fish ...
I don't think iLink would allow follow the contour on the built Contour XD anyway ... That's only for the LakeMaster cards ...
