Yes I did. I bought the extented warranty when I bought the car but the dealership told me it did not cover the stereo. This did not make any sense to me so I called Infiniti and 3 days later the dealership called me back and said the stereo was covered and it was a misunderstanding when they had checked my warranty. They replaced the stereo last week. They said to replace the stereo was around $1,800 so I was already looking for a place where they fix oem stereos. From what I saw they all were asking around $300 in the houston area. Have you looked into this? Good luck fixing your stero, Oscar.
