hey people!! i have 2010 Tucson, was just wondering if the stock radio has a secret button that has to be press, here's the problem lets say I'm listening to the radio at volume 12 -15 range and i get home turn the Tucson off and when i restart is there a way to get the volume of the radio starts a 3-4 volume power like my old Santa fe use to. thanks Tucson people !!!
