probably. It will be very expensive. I did this for my old 330i. I see no navigation retrofit kit in the BMW parts catalog so that means you would have to order all the individual parts yourself plus new wire looms that have the wires for all the the options you currently have plus wires for the nav. They won't sell you just the wires necessary for navigation until/if/when they make a retrofit kit. You would have to research and figure out yourself what parts would need to be ordered. If you walk into a BMW dealer parts department and say "give me all the parts I need to retrofit the nav" they won't know the answer.
