First, establish your budget. Otherwise, you are just on a fishing expedition.
Then, go to Crutchfield.com and look at the head units available within your budget. You will also need an interface unit to seamlessly connect your new head unit to your truck while maintaining steering wheel controls and other interior integrations, without cutting any wires. These interface units are also available at Crutchfield and will cost around $100-$150. If you have additional questions, call the Crutchfield Techs on the phone to get answers. Even if you end up buying elsewhere (Crutchfield is very competitive pricewise), you can get all of the information required for you to make your decision using Crutchfield as an information source.
