OK thanks Brian. Managed to find them without taking out the console.The big black one is the one for the OBC clock not sure for white one.
The obc black has a locking/extraxtion clip so have a look how it works. I think the clip on yours is in the locked position.
The clock i removed just pushed out from behind with a finger from the switch hole next to it.Not sure how the Square OBC clock is held in but the round one on the later cars is held in from behind the console so access is difficult without taking it out. @Faheem should know as he has just fitted his.
