I'm a gold lifetime member, but I've yet to have a single route work for me in 2 years
to use it, you have to turn off calculations on your GPS, so if you wander off route for fuel or a cafe you get lost.
if you do see your route on the map you can end up following it back in the direction you came
turn calcs on and it totally ignores what you planned and takes you straight to your destination.
I've experimented and tried hard to make it work because it does look amazing, and others swear by it.
I still use MRA to plan routes, but never send anything to my GPS (BMW Garmin Nav 6)
After the route is planned, i pick out several parts of the journey, manually input them into the GPS and store as favourites by number the day before i leave.
1 is start, 10 is the end.
all other numbers in between are POI or cafes etc along the route.
This way i can just leave auto calc on and it works perfectly.
I would try a route or two while on trial and see how you get on.
