Well that is a bit far for a beer - could you ship it here?
David - start by removing the rear cupholder. open the unit and then using one thumb push the unit firmly to the right. At the same time hook the other thumb inside the other side and pull gently toward you - you have to overcome a plastic tab - they break if not careful - that is why you have to push to one side first.
Now pull the vent unit straight down, past the tabs at the top - then pull straight out.
Now you will see 2 screws holding the existing armrest in place (just behind where the top of the vent was.
Remove these and the armrest unit will lift out.
New unit simply goes in it's place. There are 2 extra nuts you have to attach to the new unit - you will see where 2 screw attachment fasteners come through the bracket opening on the back of the tray compartment - just below where the other two mounting screws are - these new onees are to support it when it is open.
I have no information about the latch at the front ( I never completed my conversion because I was experimenting with trying to have the lift up unit - but keep the telephone - could be done but required more hardware modifications than I felt I wanted to make.
Hope that helps.
PS - there is a spare power connector down below the small storage box - near the ash tray (used for the light for the replacement casette box) - you can use this to connect to if you want to put a small light in the armrest tray.
Cheers

Anyway, now that I've vented...here goes:
1) remove rear cup holders/vent
and unscrew arm rest(see posts on bmwtips.com)
2) pull up boot around shifter and unscrew the two screws there
3) now the trick...start lifting the trim from the side closer to the front
of the car. Once you have enough room for your fingers to slide below the hazard
switch...push it out toward you.
4) You will now see the secret screw. With the screw out, pull the trim unit
up and toward the from and the entire assembly will come out easily...make sure
you disconnect the wires to the hazard, ashtray and door lock.
Don't have a digital camera but it's really quite simple.
