Looks OK to me, but....
You'd maybe do better flogging the device to someone who likes it. There are several bods on this site who claim it's the best GPS device ever made; they'll buy it just to have a spare.
Failing that, advertise in the pub and in the Wanted section, that you are after a power lead. Chances are someone will have one and maybe even the cradle kicking about. I gave one to Mike P years ago.... but he's gone to the great beyond.
