Can't seem to reset oil service light

[asma123]

Hey guys I got a 2002 x5 4.4.
I replaced the cluster and the stereo (original did not come with navigation)
Anyway everything works great but I just noticed that my oil service lights weren't changing so I tried to reset it but I have no option to reset it.
I pressed the button and moved the key to the 1st position. The oil service does come on but there's no option to reset it. I had my oil changed about 5k km ago by a drive in shop. They were able to reset it but it's just stuck on the all green. Any suggestions? Could this be caused by the aftermarket stereo?
