Well just found out my Helix uses a micro sd card. My Navionics Hot Maps premium in my 798 is SD. So I will need to get a map that is Micro. I am seriously looking into getting Auotchart Pro and do my own mapping. I have been reading it is better then the paid maps when you do your own. The feature where it shows hard or soft bottoms seem nice.

Anybody using Autochart Pro?
