Jason brings a good point in his post about using a pre-release LakeMaster card in his 1197 unit. The older units may not be able to handle these as well as the new 1197, 898 and 998 units can due to the speed of the processor. We have not received any of these cards to try yet (boy, you must be connected Jason!) so all I can do is speculate about it at this point. The fact that you will be able to do things with the data the LakeMaster map cards will be showing on the Humminbird units tells me that it will take more processing power to do so.


Roger R,
I have not heard anything about upping the warranty period.
