IIRC you have to download the PCC app to your phone - you then set up an account wit you email ad a password - hopefully the rest will fall into place !!! (it was over a year ago since I did mine)
Just dowload the app, put in the code that your dealer sent you (this means the car has been pdi'd and you must have sent them an activation code already?) and the app on you phone will show you your car.
