Canon GPS unit to fit EOS-1D X, EOS 5D Mark III, EOS 6D, EOS M, Rebel 4Ti, or any later model that displays [GPS device settings] in its Set-up menu. Barely used, this brilliant little device is supplied here with original packaging, protective cover, and unused carry pouch, cable, manual and software CD. I'll even include the AA battery because that's the kind of guy I am. Happy Bidding.
