Cigerette lighter help?

[JoeG07]

Dunno if any1 else has this problem, but on my polo, due to the cigerette lighter being directly in line with the gear stick, whenever i am using the sat nav and i put it into 3rd or 5th, it knocks the bugger out and turns off the sat nav, which is SO p*** IRRATATING when your at a junction and you knock it out and are like "ARGGH WHICH WAY NOW?!"

so anyways, is it possible to buy one of those cigerette lighter multi plugs and cut off the lighter input on the end and wire it straight into the back of my existing lighter? Or is there something in the socket like a transformer or whatever that means it can;t be wired straight in? Or can i wire my SATnav straight in if i cut off the end of that wire?
