[https://www.ifixit.com/User/2529700/ttsenkumar+kumar|'''++ttsenkumar kumar++'''] not quite sure which slot you are talking about. I suppose you are referring to the rear camera slot. You can always post some images of what you are looking for with your question. Use this guide [guide|21499] for that. That is most likely proprietary and without a proper schematic it will be extremely difficult to source it. I do believe that there is a rear camera kit for your navigation model Check for something like YESFX999101
