Hi everyone, just joined up as I have tried to put an aux into my punto and I have followed all the steps as advised. Bought the cable with the yellow end and plugged it into the back of the CD player, it works but only when clicking the windows button on the steering wheel, then after 30 secs or so it just switches back to the radio (or tuner) as it says on the head unit and no longer plays the aux input. Can anybody help :/
