Dumbo questions:

1) I have a regional image downloaded of the UK from pg 1 of this thread as well as the 3D image. But when I try enable 3D on my Garmin Oregon 450 it tells me there is not enough altitude info on the map.
Is there another file I need for altitude info or is this map 2D only?

2) I have loaded a Mapsource route from a to b and downloaded it to my to my gps but when I try and activate the route my gps complains that there is no routeable info on the map!
My last fix position was in Japan and have removed the Japan maps. Is this the problem or are these Euro NT maps not routeable?

Thanks guys and sorry for my ignorance!
