doesn't really have "greater' functionality still completely archaic, wooh it has bluetooth! big deal you can't even stream from it
get the wireless headunit and you can have waze or google maps going and stream music at the same time, or have front and rear movies or roku, fire stick, chromecast, hell you can even mirror a pc to it if you really wanted to. I have the pioneer nex w8200, maestro rr, does front and rear video in unison or I can have the rear separate or the kids can hook a xbox to it or whatever, threw a hotspot in the center console, good to go the deck has hdmi or we can still use the factory rse composite connections for the rear video, I can have the rear audio on for the rear video or they can use the factory headphones and still have the radio playing in front, the maestro has a obdii interface so any check engine light and the code pops up on the radio, tpms, digital gauges, retains the bose and fade and digital surround.
