Yes, but that's an easy one.

Sit in the drivers seat and turn towards the passenger side. Grip the knob withboth hands and yank upwards sharply. DO NOT lean over the knob when you do this or you will be sporting a black eye or missing teeth

They do come off quite easily with a sharp pull. Just pulling slowly, even quite hard won't make the knob come off, but a sharp upward yank will.

I replaced my knob only a couple of weeks ago as I managed to get a brand new TitanII trimmed one for £10 off ebay!!

Next job is replacing the ULF with a Gen13 one so my iPhone will work properly.
