I have an 07 Titan SE KC and want to upgrade my stereo. I dont know alot about all the different options or what they do. I have looked online :computern and am pretty much clueless about what most of the stuff means :crying: Im basically looking for either a single or double din unit that can play dvd's and cd's, possibly hook up a rear view camera and navigation, and run either xm or sirius. Maybe bluetooth? If I do get something navigation ready...what exactly does that mean? Do I have to run a cd to load it? And if I do then does the cd have to stay inside the unit meaning can I run the navi and a cd or dvd at the same time? Sorry for the dumb questions.
