it seems the best route is to code to Hifi, and this is done with a purchase only?
and then do the following sequential codes from the listed parameters above?
the only thing, everyone is UK, and the models definitely make these things confusion of all. I know my x5 has the lower of the years base audio. and I have no disk or grace note CD, not even a stock one. IT has a grace note in system in hidden menu for the original programming, and I have the model that shows up as no programing available via interface. so I am not sure what to do at this point.
