Hello, I recently bought a Lowrance Hook 5. I downloaded IMC and successfully created AT5 files. When I put the SD card in the Hook 5 and power it on, this happens:
1. Unit starts up and displays the basemap.
2. After 15 seconds, there is a short beep.
3. After this beep, the basemap will only display when zoomed out (scale >= 50 miles).
4. If I try to zoom in, the map is blank.
So then I tried using the Sample file that comes with IMC. Exact same result. I tried many different combinations: encrypted, unencrypted, root folder, not root folder, big files, little files, etc.... always exact same result.
Question 1, is IMC compatible with the Hook5? The Lowrance website says "The free, unsupported Insight Map Creator (IMC) software allows a consumer to create unencrypted .AT5 formatted maps for use on all current Lowrance multifunction displays and chartplotters." which implies to me that it should work.
What am I doing wrong?
