Hello,

I recently purchased a Humminbird Helix SI/Gps finder and have been looking to purchase a Lake card for it. Here's my problem. I fish mostly in Kentucky and Alabama. This would require me to buy the EAST and SOUTH regional navionics cards. That putts me at over $300 in lake cards. The lakemaster card offers no lakes that I fish. I bought the Helix thinking it would take the Navionics plus card where I can just download the lakes I want and it's not region specific. However Navionics decided to change the new PLUS cards to a 16 Gigabyte card which is not compatible with the Helix SI unit. It will however take the older PLUS 2 gb card. I cannot find the 2 GB card anywhere. All the retailers online I've checked are selling the newer 16gb cards. Can anyone point me in the direction to get one of the older 2 gb cards? thanks
