Hey - any luck with this? I have posted in another thread that i retrofitted nav and got a harness from what i believe is an older X5 (03 or 04). I didn't go the retrofit harness route.

So when i plug in the module (not knowing i didnt have ulf or what tcu was ) everything goes blank. Is this likely if there are issues with older models using the TCU? Essentially if this is an older harness it goes back to older model in terms of wiring correct?

So OP - how did you get TCU working with an "older model"?
