Need for Speed Carbon: Own the City Q&A

I've beaten all the tracks in story mode for own the city, but the only thing holding me back from beating the game are the crates. There are crates hidden through out the free roam, I've found 28 crates out of 30. I can't find the last two, and I was wonderin...

How do I find the cheat menu or the strat menu?

how do you enter cheats?

how do you enter cheat codes in need for speed carbon own the city for psp

ask how to sell your cars

Where do you put the cheat in? Where is it?

is there a code for unlocking every upgrade for your car
