Gonzalez has signed a six-month loan deal after spending the end of last season with Championship side Leeds.
Craig Brown's capture of midfielder Chris Clark was swiftly followed by the signing of Gonzalez after the Dons received official clearance for the player.
The Colombia international goalkeeper had spells in South America and Turkey before moving to Manchester City in January 2010.
The 28-year-old will join up with his new team-mates at the Dons' pre-season training camp in Holland next weekend.
