New to this Mini thing
 

Just bought a 2015 Mini Cooper S convertible for my wife, She has wanted one from day one. the car did not come with a back up camera or navigation, can this be easly added ???

Welcome to MINI Cooper Forums! Congratulations on the purchase of your F57. You can definitely go back to the dealer and ask them what it could cost to add those upgrades onto the vehicle as I believe they might be able to do so after the fact. I'm not sure about the navigation though. You could always install an aftermarket unit if they say no. Got any pictures?
