hello, so I grabbed this from a VL3500 I patched for fun in the offline, but how can I set up color thumbnails like this for scrollers? I've seen it done with Wybron Forerunner 7", but I have no idea how to do it.
In patch, create a multipart channel with a scroller as one of the parts. Select a standard scroll in the attributes tab or build your own custom scroll. It is covered in More detail in the manual and the video tutorials.
