Small annoyance:

My hihi pro stereo displays 3 phone numbers. service, assist, and bmw.
The radio has the previous owner's dealer phone number programmed in the service slot. I've RTFM and can't find a way to change it.

Is this something the dealer has to change or is there a special key sequence?
