Nokia HSU-3 pinouts

Hi!

I'm setting up a Nokia CARK-126 car kit for my 7210 phone, and I'd
like to put a handset on it.
I already have a HSU-1 handset which I used with my previous CARK-91,
but I've seen it shouldn't be suitable for new kits.

I also have find out the pinouts scheme for my HSU-1, so the question
is:

does anybody have the pinouts for the HSU-3 handset plug, so that I
can try to convert the old connector plug into the new one??

Thanks, Steve
