It's pretty basic.. You can copy the entire CD to the computers hard drive. There's a folder hiarchy and you'll drill down to the actually map files. the map is broken into 3 sections: west, middle, and east. Once you've found the east file you can open it and use the arrow buttons at the top of Acrobat to navigate back n forth ( or in and out ). It's certainly not the same as the CD was designed but it's workable. I've taken screen shots and built my own set of " Fork Milk run spots" and save them to my iPad/ iPhone as picture files. You could also save them as PDFs and open them with iBooks on your iOS device.
One more thing I'll re-state.... Martin's Map CD was built on Adobe technology that's over 10 years old. The CD does not work with current Windows OS PCs either because Adobe has updated Acrobat several versions since the original Martins Map CD was produced. As an example... How many of the guides that helped develop that Map are still around? ( I mean no disrespect to any that have past away, but proving my point that although a very cool tool, it's dated )
Here's an example of a pic I have on my iOS iPad & iPhone:
