Interrupting/re-entering a route

What I typically do is put alerting waypoints somewhat downstream of where I think the point of re-entry from a side trip will be. Then when restarting the main route my 3597 gives me the option to "select next destination" i.e. the next downstream waypoint on the main route. It will do a recalculation from the present position to that next destination waypoint and then continues on the main route.

Does your GPS provide you with the "select next destination" option when activating a route?

The GPS does provide that function. However, my POIs are not listed when I look at the Route Properties file. Only the shaping vias show up, and I have set these to not alert. I would have thought the POI information would transfer into the Route file. Looks like I need to manually enter this into the Route. correct?

I think you'll need to create POI's as waypoints, then insert them into your route. To turn a Basecamp map POI into a waypoint either double click on it and select the waypoint icon or right click it and select new waypoint. That will create a waypoint at that location with all the details of the POI. Use those in your route and see if that works for you :confused:

Yes I enter the via points manually and set them to alert; then they will show up in the "select next destination" list... These are also handy in that you can have the GPS display the distance (or time) to the "next via". I like to use these on long trips especially as we approach the end of the day and have to make decisions whether to stop for the night at the approaching alerting via point or, proceed on to the next via point. In remote areas some small towns have no accomodations, so the alerting via points are researched before hand to make sure motels, etc are available..

Took a while for me to learn how to set up my 3597 compared to my older GPS while had only route/waypoint capability. In terms of inserted shaping points (non alerting) and manually created (and set to alert) waypoints, what works well is to rely on non alerting shaping points to keep the route on the desired, typically blue highway, and only use manually inserted alerting via points to indicate distance/time to major milestones along the route.

As indicated above, regarding POIs I make a via point at that location if it's a place I plan to stop and visit so the usual alerts and guidance is provided on the approach.

Also I've learned to not put any alerting via point on top of turns/intersections on the route as that can interfere with the normal GPS alerting and indicating of a required route turn information.

btw this is all done in Basecamp and then uploaded into the GPS.

I think we are getting somewhere. All the POIs were originally created as waypoints on the routes. I just modified the icon and added proximity alert information. Right clicking or double clicking the icon brings me to the properties/notes/references dialog. I have found a couple that do note that the selected waypoint is in a specific route, and they do show up in the route properties dialog. However, most of the time, there is no note that the waypoint is in any route.

I may have a terminology issue here. I assumed I have created POIs from the waypoints along the route. They appear along with the routes in the "Adventure" listing detail on the left side of the Basecamp dialog. However, even if the POI/waypoint has an address directly on the route, it does not show as part of the route properties.

Right clicking on the icon does not allow me to create a new waypoint.

I think there's a problem with terminology here which isn't helping. You talked about POIs initially but now you're talking about waypoints. POIs are embedded within the map, waypoints you create.

OK. My POI's were all custom POI's that I created from waypoints. I exported as a .gpi file to the Garmin.

What works is to right click the route to open the route. Then, in the properties dialog, select "insert waypoint". This brings up my custom POI list of waypoints, from which I can select the appropriate one. It is added after the last entry in the properties. From there, I drag it to the proper location and recalculate. Seems to work.

Now that I can get the waypoints associated with the route, I will use Dandeman's suggestion to set up PIO's as waypoints to indicate where to return to the main route. Thanks to everyone for the advice!

Great, glad you got it working. I'm still slightly confused though by what you say you're doing. AFAIK Basecamp won't read custom POIs from your GPS, so when you say "right click the route ... this brings up my custom POI list of waypoints' which 'list' is this? Is it a list of the .gpi file on your Garmin or is it the waypoint list in Basecamp? The latter I can understand, the former I didn't think was possible :confused:

AFAIK Basecamp won't read custom POIs from your GPS...

Sure it will :)

It won't read, or I don't think so, Garmin Safety Camera POI's but my custom ones show up.

You can turn them on and off so perhaps yours are disabled,
