Yes, I can see tide data if I switch my chart source to 'C-Map USA' in my EVO3. However, I would like to be able to see the tide data in my databar as I am using my custom chart with satellite images without having to switch chart sources. . I know I can use my phone for tides if I have to, I just thought it would be nice if I could add a tides folder to my custom micro sd card. I'm pretty sure it's just a bunch if data that gets read by the EVO3 based on your location.
