Can anyone give specific advice for a non-tech person (me) who owns a 2016 Hyundai Elantra Limited and would like to add car play to it? —I know you can go to BestBuy, Crutchfiled or an Car Audio Place, but what is the best thing to do to ensure everything works and ones dash/car is not messed up. Price- refer under $500, but am willing to pay whatever - but ex - now I my navigation system has a back-up camera, so do I need it replaced- would it be replaced? - Prefer for new -whatever - to play CDs. Thank you in advance.
