Hi guys. Have two questions here: 1. Can a Sedan car use rear passenger doors' doortrim from a Tourer? Are they the same? Or they are totally different? (dimension wise and location of points where clips/latches are being used). 2. My headunit is the non-satnav version and has "CD/AUX" button on it. Without me detaching the headunit to check the rear ports, can i use accessories like Grom kit/Xcarlink/Yatour so that I can play music from SD Card/USB/MP3 player as well as using the controls on my steering wheel? Thanks.
