Travel via..........

[Jaded]

Hi, I have T T installed as an App on an iPad. I don't know how to identify the version. Q - I plan a route, T T provides it, but I want to modify it. For example, the route provided means leaving the M 25 at J 15. However, I want to leave the M 25 at J 16 rather than J 15. Motorway junctions are obvious (IMO) points of interest, but I cannot get T T to accept it as a 'Travel via' point. Grateful for any help. J
