Jquery slider with holder image??

https://www.tomtom-extras.co.uk As you can see i have run into some problems trying to set up a slider in the place i want and other things, not only did i need it more to the right but i was needing it to have a surround image of a gps device so it looked like the slider was inside the slider.
Could someone please advise how i change the position of the slider and please if giving css code tell me exactly where in the css i need to insert etc.

And if anyone knows a way to have the image behind the slider or surrounding it that would be so helpful, thank-you.
