Course limit on 1030 Plus

Have you tried the filter on just your courses? Several options available that should pinpoint the course you are searching for rather quickly. I don't have any courses by others showing up when using the filter.

Not yet. I don't keep courses on my device.

One reason it's "rather quick" is because the list isn't too big.

Agreed - I just discovered this while researching why a new course wasn't being added. You press "send to device" and the sync finishes, but... nothing happens, it just doesn't appear in the list.  Would it really be too hard to display "Course limit reached. Please delete courses to add a new one" ???

It's fine to have a limit, it's not fine to silently enforce it.

It is outrageous how bad and arbitrary this device is designed. What is the point of having a lot of memory if you can even store more than 100 trails on the device? I understand that there is a real limit when you run out of memory but just setting a threshold to 100 makes no sense. I like to store and keep as many trails on the device as possible. Garmin, please fix this. 

I think Garmin's thinking on this issue is that with Garmin Connect available to easily download rides, why have the Edge hold them all. The Edge no matter what model has such a small screen that it is difficult to scroll through all the rides.

Secondly, you might have noticed that the startup time is much slower when there are many courses and rides on the device. It has to go through processing them each startup. Unfortunately, Garmin has a fairly weak file structure that is not nearly as efficient as say a Android device.
