Rb clio 200 sat nav question

Alrite guys I pick up my rb tommorow and having a quick browse through eBay I have found a cheap in dash sat nav removed from a 10 plate 200.
Would would be involved in fitting this to my car. Im a tech by trade so I understand the dash will need to be removed which isn't an issue but would I need to activate the sat nav via clip? Or anything like that? Ahh help appreciated.
