what files do i need to run from sd card ,i have maps etc

Have you unlocked your device or run other software on it before? If you have then just download a copy of iGO then run it on your device as before.

Put one map (.fbl) in the content\map folder to start with.

have tomtom latest map on at moment but very slow.I downloaded your files package but does not load

Which package? And what is the specification of your device?

all sorted works well better than tt much quicker

Tomtom navigator will slow down considerably when you have a large number of poi's (like non official speedcams) and voices installed
