Mobile Car Kits in the Focus: where do they go?

[b2tf]

Putting a car kit for my phone in soon and part of it (genuine Nokia kit) is a cradle which holds and charges the phone, so obviously it's going to need connection to power somewhere.

I'm assuming it attaches to the centre console where the CD player and HVAC controls are, but it's got me buggered as to where it'd connect - im not allowindg any holes to be drilled and i dont want any obvious attachments.

Has anyone had one put in, if so how's it all connected and where does it all end up?
