Fused permanent 12v feed

Hi all,

Fitting a simple GPS tracker to my S2 and need a permanent 12v feed to keep it charged, preferably in the cabin, but obviously must be fused. Any suggestions? Interior light? Electric windows? Something at the fusebox?

Cheers guys, I wasn't going to bury it, just a bit of fun as it's a £30 ebay job. Live to the stereo makes the most sense I think.
