I’ve just tried the anti theft service pass off and hidden button - on the link you just sent - it worked, and it even let me reset the password.
thank you all who have posted over the years...wasted a bloody whole day today just to fit a reverse camera which the trip the fuse...hence password reset needed.
Funny thing is I set the password 12 months ago and even gave myself a hint...which for the love of me didn’t have a clue!!
phew...all done.
