Thanks
Hot maps Platinum comes with SonarCharts/HD layer preloaded. You can not add anything outside its coverage area. But lets Navionics goes out and maps a new lake thats not on the card it will be aded thru the Freshest Data program into the SonarChart layer. Make sure you select with the Fish n Chip or SonarChart setting on your sonar
Pretty much all mapping updates are done thru the SoanrChart layer
I would recommend doing a freshest data upload to your card monthly to get the newest data from Navionics.
