Hello I am new to this forum and this is my first post. Today I had best buy hook up the D-3 and my i-pod is the only thing that works right. When in the navigation mode it shows me where I am located, but the option to type in the address and POI and many more things are not working. They hooked up the camera as well and that kind of works when it wants to. It will work in reverse, then I would try it again then it comes up all black and and says that this camera might be shown in reverse. I would appreciate any help at all, thank you in advance.
