I bought a 2011 Versa last month and I really hate the lack of 12v Power Outlets. I'm a Brit living in Virginia and I hope that the Versa over there has the same interior as mine - if not please ignore me and I'll go away!
Anyway, I found this on EBay -
http://www.ebay.com/itm/Car-Charger-Pow ... 4cfc0c1523 there are loads of them, mainly in Hong Kong and I know that they'll ship to the UK.
It fits exactly (and I mean
exactly) into the oblong hole behind the handbrake and will give you three 12v holes and one USB. I didn't actually buy it for this application - I lengthened the cable and installed into the little compartment above the radio - I removed the panel around the radio, made a decent sized hole in the back of it and the power outlet wedges nicely right at the back. I now have my GPS routed under the dash and into this cubby hole and you can't see the cable at all.
I'm ordering another one to put in the hole behind the handbrake and that'll give me 5 12v holes and two USB - more than I'll ever need I'd have thought. I'm not a seller on EBay in case you're wondering - just felt I had to pass this tip on. It actually cost me $5 delivered which is a hell of a deal for something so useful.
