Fix For Custom Soundtrack Glitch In Midtown Madness 3 
There seems to be a glitch that will play the first 2 songs then play the same song over and over in the game. This is for those who want to use the custom soundtrack and are having this problem. First select songs and make a soundtrack or if you already have then do this little trick. Go to the cruise mode and just run around or let the game sit while leaving it unpaused. For some reason this mode the soundtrack actually changes songs. Let the songs play through about half way Ex. If you have 10 songs on your list let 5 play completely. Then go to the Blitz mode the guy who starts the race always has something to say if he is saying different things then this is a good sign. Start the race and finish it listen to what song is playing and then either restart the race if you did not beat it or continue with the next one if the song is different then you know have the glitch fixed. You may need to repeat this trick in cruise mode but it will work. Then once the songs seem to work they way the should reset your Xbox and try the game again in a race mode. Your music should now function the way it was meant to. Xbox is working on a patch but this trick will keep you from going crazy listening to the same song.

(Both cars require the Koenigsegg CC) 

To Unlock the ASP: 
On the Northern side of the La Siene river, on the right side of page 23 in the manual, there is a jump bordering the river, and the paintcan marked ????. Start on the far right side of the river with the Koenigsegg CC, and gain as much speed as possible. When you hit the ramp, the speed should launch you to the ASP.

Easter Eggs:

1920's Movie Easter Egg 
In Washington, go to the Lincoln Memorial. It should be Near a reflecting pool. Drive up and go inside, and drive to where you can face the statue using left or right on the thumbstick. Wait around 20 seconds, and the screen will look scratchy, and everything will be at least 3 times faster. 

Old Paper Easter Egg 
In Paris, Go to the glass pyrimids. they should be near the river in a big white spot on the map. Do the same as mentioned above to the pyramids, and the screen will become Tan and Black, like an old drawing. 

Another Easter Egg 
In Washington D.C., look for a large gate that leads into China Town. It is near the construction site. To the right of it you will find a wooden wall with a yellow graffiti tag on it. Hold up on the right thumbstick for approximately 20 seconds to get a sketchy effect.
