I used to be a lover of MotoGoLoco, until I realised it will only plot the waypoints and not the intended route (unless you plot a bazillion waypoints).
This was my finding on a Nav V.
I now, after my lesson the other day, prefer to use route shaping. It's so much easier and quicker when intending to use on a Nav V.
Obviously, if I'm going to share a route to a multitude of devices, then I'll add more waypoints.
I've worked out over the past 9 years of using Garmin products that waypoints are waypoints and route shaping can be read differently (or not read at all) by different devices. This (I agree) is a lot to do with preferences in the map creating software AND on the device.
We have a simple rule when riding by satnav.
Leader takes precedence.
As long as everyone has the destination then all is well as we tend to do Top Gear rules when on holiday. As long as they have a mobile signal then we just bugger off. lol. Everyone has breakdown cover so it's up to them to sort themselves out. It adds to the adventure.
ps. I use the term Waypoints because that's what my MapSource and BaseCamp calls them.
On my Zumo routes are saved as routes & waypoints are saved as favourites. My device does not recalculate unless I allow it. There would be no reason to use BaseCamp to plot a route if the device chose the route for you.
If my device asks to recalculate & I say no my routes keep identical to BaseCamp so no recalculation was carried out even though it only sees my via & waypoints.
