Why not just create two routes, like I suggested, and activate whichever one you will use or are using?

because sometimes you may have multiple routes that share a section. I'm lazy and I don't like to do it by choice. anyway there is no other choice.
I thought I may be possible that GPS treat with routes like a (city) network and do a simple navigation like it does routing by a map.

Yes, I agree. I guess the problem is that he is doing this on the fly, but I can't quite figure out why it must be done that way.

Knowing what I know about GIS and its programming (and GPS treats tracks and routes similarly), it has to do what it does to create lines and polygons. The GPS itself just collects positions. It's the software that instructs it to either (1) leave the positions as is or average them into a single point (2) connect the positions with a line segment (3) do the former, but upon closure connect the last position to the first to close it (mostly in order to calculate area) Thus the multibranch figure is a bit above its ability. It would require (as GIS does) a database in the background that would allow multiple lines to be viewed as one layer and would allow those segments to have other segments in common. The software maps as well as full blown GIS can be uploaded into a GPS, but you just can't do this on the fly. For that, you would need something more on the order of regular computer with the software and interactive capabilities of mapping software. Trimble makes those - they are basically handheld computers with GPS capabilties, but a touch pricey (JUNO's start at 1500$ plus software)

Till now, I create each route separately so I have 2 (or more) routes on the shared section (right). I want to know if I split such Routes at shared section and create a only one route in that part then I'm still able to use routing functions only in 1 stage. (left)



This needs GPS can join virtually 2 (or more) routes but make it easy for me to creating routes specially with long shared part.

I'm not sure if it's possible so I asked if anyone knows. btw I use colorado300 if it matters

neghafi, I think that the problem is that in the right draw both routes don't have the same waypoints on the C-D section, so it wouldn't be impossible to join them

Sorry Diego but I didn't get what you meant. I just want to mention there is no problem. It's a case of doing something more easily

The problem is that it can be done easily mate. The solution is the draw to the right

if only one routing is considered YES only right is available. but left option is OK if two stage routing can be done. I wish Garmin make left option available by only one routing too.

It's only a wish wich can't be fulfilled, sorry

I believe it's possible as possible in routing of routable street maps

How is it possible

Possible as like in routable maps. routable maps has separate links (roads) and when defining destination the GPS will try to find the shortest path (of roads) to the destination. it means that, it can find all reasonable routes to destination and find the shortest.
Now just imagine if it can do a same thing (finding reasonable routes) by using routes instead of roads.
It is possible!
