GPS Plus Addresses..

I'm not sure what the aim is here, "All Addresses Departing from the same address", sounds to me like :-

1) Start at 'A' and go 'A to B to A to C to A to D to A to E to A'

however it is more likely that what you want is:-

2) Start from A and visit B, C, D, E, strictly in that order

or

3) Start from A and visit B, C, D, E in any order that is most efficient

On Garmins you can do 1) and 2) above with a function called 'Trip Planner', where you can have a start + multiple vias + an end destination. If you want 3) above on a Garmin you will need another function called 'Route Optimisation'

If your Garmin doesn't have Route Optimisation, you can generate an optimised route on a computer program called Basecamp and then download the route to your Garmin device, it may also be possible to send the generated route to a non Garmin device

 

Yes, so its option 3) that you want, I have the Garmin Nuvi 56 which is pretty much the bottom of the range as far as price goes and that has Trip Planner with multiple vias, it also has route optimiser so that it will re order A, B, C, D, E into say A, C, E, B, D if that is the shortest route, you can also put A in as the final destination as well as the start point
