Test Drive Unlimited Easter Egg - Secret Island

See this video that I didn't made: http://www.youtube.com/watch?v=vHMBBpzeD0s
It contains the easiest way to get it.
You have to get to the little E like at 30 mph/50 kmh or it won't work. If you have a big screen/Xbox 360 version you can actually look at the spot. You can also read my very own tutorial:
1. Get a fast car/bike (Saturn Sky ISN'T a fast car)
2. Zoom at the right bottom of the map, you can see a little blinking light. Mark it on the GPS.
3. Near there right side, it's a little street usless that shouldn't be there. Try going up that way.
5. Drive at the blinking E at 30 mph/50 kmh or it won't work.
6. Enjoy the island. There is another E so you can go back without touching the GPS.
