I just got a lowrance elite 4 hdi ff/chart plotter w/Gold navionics sd card...Please forgive the excitement throughout the following, moving up from a garmin 550 with bluchart and spots i've been to on others boats, i'm like a kid in a candy store!
1. does the sd card used to upload the spots i download from your site need to be formatted a specific way?
2. is there a special sd card to use? (can the photo ones work or is it a data card)
3. can i upload the card with file folders labeled for instance wrecks 2-5 miles out, wrecks 5-8 miles out, west wrecks, east wrecks, etc. and have the ability to draw from the specific file the area i want to fish that way i can reduce chart clutter?
