First, steal a cherry poper car, and turn off the radio. (I seeing them alot near middle park).
Then, press the horn bottom, and listen to its sound.
Press again and again, to change the sound.
One of the bits is the GTA theme (to recognize it, drive the cherry poper fast).
When the car is playing GTA theme, call zit, and they will tell you the name of it (you already know). ZIT: 9485550100
You will also get the health cheat. to us the cheat again, check your phone under the video editor, instad of steal the car again.
Warning! its disabling you some of the archives!
