I need to add a X,Y coordinate grid as a layer to be put on top of my geological map. I couldn't find an easy way to do this in the forums, so I hope someone here can help me.
I do NOT have a lot of experience with ArcGIS, so I would need a step-by-step tutorial on how to do this. The map I have already has coordinate data (sample points and so on that I've added to the map are based on GPS coordinates) but I am not sure how to visualize the coordinates as a grid.

Any help is greatly appreciated.  

Edit: Forgot to add version, I'm running ArcGIS 10
