Any ideas on this one. I was out of town for a month and when I got back I had to jump start the Titan. Then I didn't use it for another 2 weeks and had to jump it again. Battery is all charged and everything normal now except when I set the clock it won't run, I drive around and it just stays where I set it. I thought maybe I'd disconnect the battery and see if it would reset something, unless somebody here has something for me.
