I have managed to gain a map of the motorway network from San Javier to Vera from the toll booths on my most recent journey. (I have found them to be like rocking horse sh*t when asking previously). I have scanned it and put it on my website which can be found by clicking here. To download it, just right click and select "save picture as" to a place on your pc. Sorry MAC users, I don't know how to do it for you.
Hope it helps 
Mark
