HUD like heads up display or HU like head unit... aka radio? I assume you mean a radio/nav. I went with the pioneer NEX-8100. It's a fully loaded pioneer nav/radio and it's universal like the majority of units out there. The wiring and dash kit are what make it functional with our vehicles. Those will be the cheaper of the parts. Install can easily be done by yourself.
Look here for more information.
