I am attempting to use MapKit to create a custom map (similar to this concept http://mapwow.com/) using an image instead of the google maps image. This is so we can include the gps functionality and the pins functionality. I have looked in the documentation and there does not appear to be a standard way of doing it. Is there a way to do this using MapKit or has someone found a way to achieve something similar?
You can't currently use anything other than the Google Maps with MapKit.
Dmytro has already pointed to useful links that provide alternatives, particularly the route-me library, but there's also the CloudMade API which provides another alternative.
If you want to roll your own, you may find the CATiledLayer class helpful.
You can take a look at route-me project. It allows developer to use custom map sources such as OpenStreetMap, CloudMade etc and supports pins. BTW CloudMade has a map style editor which might be useful for you
