If you are using the non-NT version of CN, I believe it is possible to transfer maps without including route calculation data. If the streets show up, but the unit won’t calculate routes, that may be what happened.
In MapSource, in the pane on the left side of the screen, at the bottom of the Maps tab there is a checkbox that says, “Include route calculation data.” It sounds like it may not have been checked when you transferred the maps. Make sure it is checked and try it again. (To save time, you can try it with just a single map segment of your local area as a test, rather than wait for a large amount of maps to load. If this solves the problem, just select all the maps you want to load and transfer again.)
If you have the NT version of CN, that wouldn’t be the problem, because the NT version always includes route calculation data. If you have the NT version, the box is greyed out, so you can’t change the setting. The greyed out box is incorrectly shown unchecked.
Oh boy am I stupid....I have been working on this for hours....no days...and all I had to do was check the box. Well thank you everyone....I went and checked the box and then reinstalled the maps and it works. Thank you all again very much. lil princess
