Hello!
What is the size of the POIs in the XT3?

I have all the POI files prepared in 80x80 pixels for the XT2, and the XT3 uses the same size as the Tread 2 (smaller), but I don't know the exact size. Could someone tell me what they are?

I need to modify all my files for speed cameras, mountain passes, lighthouses, etc.

Thanks in advance

To use 80x80 icons effectively on a Garmin Zumo XT3, they should meet the following technical criteria:
File Format: .bmp (Windows/OS2 Bitmap).
Size: Up to 80x80 pixels is supported.
Color Palette: RGB, 8-bit or 16-bit.
Transparency: Transparency color must be magenta (RGB: R=255, G=0, B=255).
Filename: Must match the corresponding .gpx or .csv file name

While 80x80 works, other users have successfully used 48x48 pixels, which is also larger than the default 24x24 but perhaps less overpowering.

Yes, I've tried the 80x80 ones, and they work fine, but the icons are partially cut off.

Thank you very much, I will try to convert all the ones I had on the XT2 in 80x80 format to 48x48

the new XT3 6.0 screen is same size as the XT2 screen, so whatever icon sizes works on the XT2 should also work on the new XT3 6.0, I don't know about the smaller XT3 4.7 screen

The screen size is the same, but the POIs are smaller. The 80x80 on my XT2 looks cropped on the sides.

I'm editing with this information from Garmin; it's about the Tread 2, but I think the POIs are very similar on the XT3:

"
poi size garmin tread 2

For custom Point of Interest (POI) icons on the Garmin Tread 2, the recommended size for optimal display is 24x24 pixels, although icons up to 48x48 pixels are supported. While some users have tried 80x80 pixels (used on older models), these may appear cut off on the Tread 2.
Technical Specifications for Custom Icons:
Size: 24x24 pixels (standard) or up to 48x48 pixels."

exactly what had happened to me
