Thanks for the input.

With reference to your comment:- "into user data and import it on the actual unit"; any suggestion where I find this on the unit as there's no obvious "tab". Or do you mean access the unit via the PC then do an import to unit.

Having got a route into Mapsource with no issues I also thought the transfer to unit would be straightforward. I'm usually pretty techie savvie and but this one haas me foxed
