OK - very good. Now I have a clear picture of how the device is to be used.
Now the "not so good news". This particular unit (Nuvi 50) was made and sold as part of the "Essential Series" of devices - way back when.
What that means is that it does NOT have one of the KEY ITEMS that I believe you are looking to use - which is called "Trip Planning" or route planning.
Trip Planning allows you (or any other user) to "Build a Route" and store it in the device - to be called up at almost any time you want - such as for your delivery route.
So a "real solution" would be to purchase a different unit that DOES include this Trip Planning feature.
Now a "work around" - which I use on one of my older devices that does not have trip planning - is to SAVE (as "favorites") ALL of the delivery stops that are made, and then pick the next "favorite" from the list - that appears closest from your current stop (that is how favorites are presented).
I know this workaround may sound like a lot of work, but it would save the cost of purchasing a newer/more advanced device.
Also, these "automotive devices" do not really record "tracks" for the purposes of repeating them - that is a function that is used mostly in the "outdoor" devices - such as hiking and such. Putting multiple "stops" is the method that is used for automotive devices - that have the route planning capability.
Please let me know what you think the best choice would be for your current situation (newer more advanced device or using saved favorites).
And let me know if you have any more questions.
Thanks, ***** *****
