What sort of car? That cable is only used in an E39. It will likely fit E38 and E46, but not X5 as the Video Module is located physically much further away, and the 8 377 436 will be simply too short.

"Part 61128377436 (Connecting lead, navigation) was found on the following E39 vehicles" ... (all E39s only)

Looking at the parts list, I'm not sure that's what you want!

Remember, TV was never a retrofit option in the USA, so USA dealers don't know what to look for.

So tell us car: type / mode / manufacture date and maybe we can help more.
