I am fitting a TomTom 720 over Christmas so it fits sunggly in the 'hole in the dash'

I will be running an output from the audio jack of the 720, the power, the TNC aerial and also maybe later an external aerial.

I will be taking the audio cable and feeding the aux input of the audio unit. I have the basic one as I own a GS.

I will be taking the power lead and trying to find a suitable 12VDC feed I can use behind the central console.

OK, there is the question.

Does anyone have any knowledge of:

1) If there is a 12VDC feed I can tap into behind the console or do I need to find the feed for the cigarette lighter. If there is what colour are the cables and where are they please?
2) I assume I should put an inline fuse in there. What value please?
3) Again. Does anyone know the cable colour of the 3 cables (common, left, right channels) in the loom I assume goes into the back of the audio unit. Otherwise I will have to trace the 3.5mm audio input jack from the back of the near the passenger area. Maybe they are even clearly labelled?

Thanks for any help or advice.
