Yes, I have spent a few hours with Autochart PC, but just don't have the time right now to master the program. Here is some information from Humminbird:

What is HumminbirdPC?

HumminbirdPC™ is a tool to help you manage your navigation data from your Humminbird units and MMC/SD cards by organizing your waypoints, routes and tracks. It is also used for updating software in your software up-gradable unit if it does not have a card reader.

Download waypoints, routes, and tracks from your Humminbird® unit or MMC/SD/Micro SD card to HumminbirdPC™, then customize your navigation data from there. Create new routes and waypoints, organize your GPX files with your favorite tracks and routes, and add icons to your waypoints. You can also view your waypoints, routes, and tracks in Google Earth™.

Use HumminbirdPC™ to personalize your Humminbird® unit and update software if your software up-gradable unit does not have a card reader.

Once you’ve customized your information, upload the information to your Humminbird® unit or MMC/SD card. HumminbirdPC™ saves your changes to your computer automatically.
