I would like to bump this thread. As you know, BMW has a free cluster upgrade program if yours is faulty in any way. Mine has some pixels on the display that have died out (prior to my ownership). I qualify for this program. Anyways, I currently have no navigation in my car. I am planning a retrofit sometime in the near future. Currently I have the low on board computer cluster. My questions is, can I have bmw install the high on board computer with the free cluster upgrade that I get?
