OK, I checked and I've got the 520, not the 510 (and not the 520+). I just had to actually use the manual to figure out where things are. Example - autopause was nowhere in the configuration or settings menu so I assumed it didn't have it. It is in the activities profile menu ... I had just assumed activities profiles was for putting in intervals or routes, or whatever, not configuring the main screen. So my bad for not finding it and other items, but on the other hand I found this on my last two computers without ever looking at a menu. This is just me being a Luddite.
The main benefit of a modern computers is the 'activity profiles' that let you store and use different settings/sensors for different bikes. You might want autopause set to 2mph on your road bike, but disabled on your MTB, etc.
