Hi all, I now have primo and igo8.3 runnning on one SD card with newer maps on primo ( want to have both running for my hols to CA next week so i can fall back on igo if i have primo telling me to go the rong way!!!!) many thanks to chas and nabi for your help...... been reading all the new post.
All i am missing is a dem file to use with igo, primo or both tha that will cover CA can any one help please!!

Many thanks once again

CA meaning California? I am not even sure there is a single state dem file.
Two things:
(1) you do not really need a dem file, it takes up lots of memory too. Only thing you miss is the relief view.
(2) we do not have a living link to dem files, and I do not have America on my PC

thanks for getting back. would just like to see it action as not any hills where i am in UK

Set out a route in the Scottish highlands and do the demo trip ;)

If I can butt in here with my two cents. As Nabi said, the dem files [terrain] are NOT necessary for the program to work. They are pretty much just eye candy and can cause errors in the operation of your nav program. To make matters worse, even though an area has terrain features, not all areas will show up on a map. It's not worth it IMHO.
