If you not have a front cigarette lighter ( I dunno cos, my car is a UK one) then you might find the option attached a better bet than your present set-up.

The lead should be long enough to tuck under the centre console housing alongside the driver's seat and I use the velcro to attach the socket to the side carpet just under the left knee rest (and so it does not obstruct the seat adjustment). Then gives me the ports for sat nav, snooper etc and the front socket I also have free for lap top or other occasional use.
