You can open the GPX file in a text editor and inspect it to find Waypoints - which will be near the start of the file and always start with Save it out as a GPX file and/or transfer it to your GPS (clear the memory first). To find out, use your usual methods to construct a short, local route - just 5 points, no more, should do it. This is probably the best method, provided of course you know what type of points your software is generating. You would do this because User Waypoints are more useful and flexible when it comes to naming, moving or re-editing them later. Method 1 - plan using a mixture of Waypoints and Routepoints. I've planned several different multi-week, multi-route trips and never yet gone beyond 1400 Routepoints, and never had any problem storing those on an older low-spec GPS. This Routepoint limit varies from model to model but trials show that the total number of Routpoints your GPS can store is typically between 2400 (for older models) and 5000. The limit is in any case only applicable to your GPS - it is not apparent in the software on your PC or online - this means that you could do a lot of planning and only discover there's a problem when you come to transfer the Routes - you will see this error message (left) - but if you don't notice it during transfer then the first you'll know is when your Route runs out half-way, on the road!. The Routepoint limit is much higher and you are very unlikely to encounter it. It does not apply to Routepoints - that is, points made by using the Route Tool (in Mapsource, and in some but not all other software). The key to all this is that the Waypoint Limit applies to 'User' Waypoints, that is, points made by using the Waypoint Tool in your software. If you use an older GPS, or if (like me) you plan big multi-Route projects for longer cycle tours - and (like me) you prefer to use direct (or off-road) routing mode - then you will encounter the Waypoint Limit, and you should read on. If you have a modern GPS model, or if you only ever plan day rides or weekend trips, or if you prefer to use autorouting rather than the direct route method, or if you prefer just to follow Tracks not Routes - if any of this applies, then you don't need to know more, you will never encounter these limits, you can stop reading now. You may need to store Routes totalling more than this number of points - here are some ways to do this. For most modern models, this is at least 1000, for older models it is often 500. Garmin GPS devices have a specified Waypoint Limit.
