I just installed a kenwood carplay deck tonight. its ok. what I dont really like now is the top screen is mostly useless . it only displays the AC info .

I was thinking about installing one of the portable units that are out now. id like to be able to read my OBDii info on that screen on the dash and not on my main audio unit(kenwood) . The 2nd display doesnt need to play sound thru the car but if it does ok. I saw this tonight
