Humminbird 997SI ????

Does anyone know if Navionics Elite SD Card is compatible with HB 997 unit???

Yes but only if; You have updated to the newest software(A free download at humminbird) and it should also work on the 1198cSI. I dont know why but it and the Nav gold or platinum will not work in the 797-8cSI units. It must be a software compatibility problem. I found out the hard way and had to return mine to Vic's for the premium software. When I replace my 797 with an 1198 I'll be going with the better navionics for sure.
Hope this helped
later
