Plug and Play with OEM functionality and look. Station/Song info will be displayed on heads-up display and navi screen. FM sound quality is slightly improved. AM sound maybe slightly improved, but nowhere near the quality of FM. If you go this route, I suggest purchasing a "Y" splitter for the antenna (1 female to 2 males). This will allow you to retain regular FM/AM signal, otherwise, you will be forced to use the HD radio mode for reception.
