BINGO!
I MIGHT have just hit on an answer.
All along, the corrupted routes look as if they have been created in the base map version of the map, not in the detailed map. I know the detailed maps for north and south Europe are loaded onto my Nav V as I can see all the intimate detail when I zoom in. BUT......
I am now getting a pop-up window in BaseCamp that says that the routes exported to the Nav V are being rewritten as the maps on the Nav V do not match those in BaseCamp. That is plainly bollox, as I can see them when I zoom in on the device and can see them on my Mac's screen when the device is connected. Nor does it explain why the route that came in from MyRoute loaded properly onto the Nav V. What it also doesn't explain is how I can create a detailed route, in the detailed maps, directly in my Nav V. Nor does it explain why I can Bluetooth a route from my XT to my Nav V and have it load perfectly. What I think the message means is that BaseCamp cannot see the maps installed on the Nav V, even though I can see them and they are listed quite plainly.
This might explain why Rustler now has no problems..... in his excellent tapping about (you can't break it) .... he has somehow maybe reloaded the detailed maps and everything now works.
I am now going to reload the maps onto my Nav V..... again!
