E36 Cellular Phone

Hello all (First thread)

What products are there for my cell phone? I have a prewired cellphone (cat 5)
handset under the center console, an old style antenna on the back window and
a microphone in the pillar. What I want to know is what can I get to make this
setup work with Verizon? I do not have a box in the trunk, all the wires break out
in the trunk but there is no box there. What am I missing and what could I get?
Can I get the BMW bluetooth kit?

On another note, what can I do with that space above the glove box? I think that
there was an optional in-dash 6 CD player, there, but I have the changer in the
trunk. So can I get a slide out screen and a DVD player there? Who makes that
stuff?

Thanks for everything!
