looks like the one for the Zumo 3xx series like I have for my 390
the right hand pin is stuck down by the look of it. Happens now and again so you get a poor connection. I lube mine with WD40 a couple of times a year then prod the pins with a meter probe to give the springs a bit of exercise. Happens more often if you leave the cradle on the bike without using the GPS and don't flip down the rubber cover.
