Where to get a headunit repaired?

[KMS]

My kenwood x693 died out and I'm thinking it was one of the little gold pieces on the stereo faceplate (female) I took the headunit off and looked at the female end and one of the pins were forced inward, i stick something in and it pops back in place. go to try and turn it on and nothing. I fiddle around with it for a while and like a dumbass i broke it by accident. So one gold pin on the deck is completely broken and there is no way for the male part on the face to get a contact point on the deck. So how do I fix this or where can I send it off to get repaired? I bought it around this time last year off amazon so I think there is a one year warranty from the manufacture? Anyway let me know, thanks.
