I ordered my SE1 ltr. in whit on Sunday last. I have now started to think about the reversing camera, can this be added after ordering. I have been told that my car is now in the country. I have not had time to ring the dealer and ask as yet. Is it just a matter of plugging the camera in to the radio, or, are there lots of other things to do to get this to work and therefor not possible as an after made fit.
