Samsung Galaxy Tab 4 Car Audio Aux Issue

I just brought a Galaxy Tab 4 10.1 and tried to connect with 3mm audio car to the aux in my car and it will not work. I tried plugging multiple times but same issue. Headphones work fine, my old xoom tablet works fine, my Samsung galaxy 5 phone works fine in the car with the same aux car. Is there a defect with the S4 tablet as many ppl seem to be have this issue? I got it to work once after plugging multiple times and it finally said it recognized headphones but after that nothing, even after recognized headphones popped up it still wouldn't play thru the car speakers. Any ideas?
