Why stop there? Get your modded GTA4 running through WINE on an Android phone, and then you'll have a map inside a phone inside a map inside a phone!

Turtles all the way down... ;-)
However... Regarding the OP, a Google Maps of Liberty City is really awesome though. Imagine if someone hacked the cellphone in the game to run off an Android emulator rendered to a screen overlay, and link it with the Google Navigator app (that's a significant modification to the engine though so I don't know if that would be possible, and especially not on multiplayer LOL).
