how do I transfer Google My Maps user content to ipad "Maps"

[[email protected]]

I have at least 20 city maps under my Google "My Maps" with user created content such as hotel or restaurant locations. How can I transfer that content to my iPad to put on the "Maps" app?

Also, is there a way to have/show multiple pins on 1 ipad "Map". I know I can bookmark each pin, but I'd like to see all of my pins on 1 map (like you can w/ Google "My Maps"?
I can't figure out how to do either of these functions.
thx,
