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.

There is no money cheat for some reason but if you really want money you can Break ATMs and such and you can also Mod the money in with a USB or Transfer cable hooked up to your Computer, to do this you can look up a tutorial on how to do it and there are programs that will help you like Modio, 360 Revulotion Horizion, ECT.

OK, I think I can slove your problem.

There is a slide setting thing on your av cord that gives you the option of using TV or HDTV (look near the end of the cord that slides into the XBOX 360), You will see two choices for settings on the cord "TV" or "HDTV".
Just make sure that you have it on the correct setting. I had the smae problem. My XBOX 360 is not hooked up to HDTV, so for me it should stay on TV. But somehow when I took out the cord I accidently slide it to HDTV.

I simply slide it back to the "TV" Setting and in about 30 seconds it worked perfectly.

I hope this helps you.
