Mapping Upgrades

[Flykai]

Hello. Relatively new to electronics but have an Elite Ti7 that has pre-loaded Navionics maps (limited customization) I typically use the C-Map social maps for my local Colorado lakes but as I travel outside of Colorado for kayak bass tournaments I am finding that the social maps aren't as helpful. If I would like more detailed maps for the mid-west, Texas, etc. What might one recommend? Thanks!
