Where do i go to enter cheats codes for madden 07 on a xbox 360

Jaxson, there is no direct code to enter for the jet pack. However, I will give you a link to the available cheat codes for 360, and a video showing how to get the jet pack. ^^ (Warning) it's not fun to get it. It takes for ever. Furthermore, I thought you were originally wanting the codes for gta V. lol So for gta 4 there is no real code for the jet pack, just a helicopter emulator mod from photoshop.
GRAND THEFT AUTO IV Cheat Codes

GOD 1

never played that one,do u have a menu option where u enter cheat codes? if not my guess is there is no code never found any button seq. code for any xbox game like ps2 use to have...

Your only choice is to go to your dashboard, console settings, memory, and delete your transformers progress. This will entirely erase all cheat codes entered.
Tip..if you choose to use cheat codes next time, turn off the autosave and you won't need to erase your data file.

Anytime during gameplay after the Gladiator Battle first set, pause the game. Enter the correct codes to unlock the cheats. A Chime will confirm the code has been entered correctly. Hope this helps.

Sorry I haven't played the second Indiana Jones yet, but on the first game you entered the codes on the chalkboard. Maybe it's the same or something similar?

you may have to unlock it

Gamefly has the controls: http://www.gamefly.com/game/xbox-360/Madden-NFL-08/125235/GameplayControls/

Meekeo has Madden 2006, 07: http://www.meekeo.com/

and http://www.replacementdocs.com/ might have it but they are down at the moment.

do you have the cords to hook it up to the interent.

Go to my madden > madden cards and then madden codes.
Unless there is more cheats I dont know about then that should work. Hope this helped :] .
