Mobile ICE installer - Surrey/ Guildford?

[.Ben.]

Trying to install a Parrot bluetooth kit in my car and have all of the necessary components:

- Head unit removal keys
- MKi9000 Kit
- ISO [SOT] lead with pre-populated data ports
- Ignition sensor loom (so that I didn't have to worry about finding an ignition switched live)

Now, I've been a bit bewildered by the process, even though I was assured it'd be as simple as 'Plug and Play'.

Can anyone recommend a trustworthy individual in the above area or recommend where I might find instructions for fitting to my vehicle (a 16V 1.4)?

Google hasn't come up with anything useful...
