Hi
The stereo in the car was designed before iPods got popular, and there is only 1 real solution that gets audio into that head unit, and that is the Dension GW 500 D2B, more details here: -

Comand Online Ltd :: iPod Kits :: Dension GW500 D2B - iPod kit for older D2B based cars

(register and it will remove the UK 15% sales tax)

The phone is more complicated, you have to take out the existing stuff and put new parts in, there are kits for 'UHI' and with the centre console parts available in the phone retrofit section on the website above - which will make it easy enough to do.
