    A while back I learned that you cannot have more than 49 points on a route.

    For the weekend ride to Mazinaw, I had downloaded gps routes (routes, not tracks) from John Harvey. When activating the routes on my Garmin in Port Perry, it displayed an error message too many points so the route would not display. One of the routes is 57 and the other is 95 points, yet John was able to use the routes in his Gamin with no issues.

    Do newer or other Gamin models allow you to use more route points?

    I'm confused. :?

    The maximum number of points in a route varies by manufacturer, model, and type of routing. it's a long story ....

    The short version is that Garmin (#1 supplier) current models allow a maximum of 50 points if the route uses "Follow Roads" type of routing, and 250 points for "Direct" or "Off Road" routing.

    Most Dual Sport and Trail rides, use Direct/Off Road routing as many trails are NOT on all GPS maps so the route is only displayed a series of straight lines between successive waypoints. It's left to the rider to decide which actual road or trail is the intended route.

    Long version .... buy me a beer sometime and I'll spend a couple of hours explaining the history and fundamentals of GPS Routes :)

    We held a few GPS Nights at the Mohawk Inn several years back, but it wasn't really a good venue for it. General "bike chat" dominates these events and it tends to drown out the finer points of using a GPS. I still have most of the Handouts I made, and they may still be useful even though GPS technology has moved on since the Garmin 60Cx was the GPS of choice, so I've posted them below (again, as they are on previous posts from a few years back).

    I have found over the years that many users don't spend enough time reading the User Manual for their GPS, or visiting the many Forums that discuss GPS. There is no shortcut - the only way to learn about your GPS is to read the User Manual, ask questions when you don't understand a specific feature, and then practice how to use the features you need. However, if you only expect to use it once or twice a year on a group ride, then don't try to master it - just learn how to load routes/tracks, and how to follow them, and use the example below, of which settings to select.

    Here's the documents we used:





    If anyone has any specific questions about their GPS, please start a new thread.
