Sentence 1 means "I'll show you some ways to get around" (The person is offering to help you navigate the city).
Sentence 2 doesn't make sense, it's not correct English. "It's got like a chromatic....." is not a complete sentence. It's got a chromatic WHAT? The word chromatic refers to colours (or possibly musical notes), but without the rest of the sentence it's impossible to say what it means.
