It is the km336 model.
Does yours have a wobbly switch? both left/right but also up/down.
I have just bought one and the switch unit/switch plate is wobbly. Upon further inspection when the unit is open, there is what looks like a triangular break at the top left of the black bit.
Amazon have sent another one today - and it is exactly the same
Please tell me that this isn't the quality that Kenwood is putting out these days !
