Guess I am the only holdout here on CD's--Use em a LOT in the car.My 2015 Toyota Highlander has a single play CD player not a CD changer.My 2012 Toyota Highlander had a CD changer.Like this better in the car.Youy have to wait for a LONG stoplight to change discs.My 2015 car has the HD radio.It works well on FM-but sadly not much to listen to on FM or AM.The radio in my car has aux analog input,digital aux input Bluetooth for phones and digital players that have it.Don't have such a thing except my IPhone-Don't have anything recorded on it since the I store doesn't have any music I want.So I use CDs,Sirius radio-yes I know it doesn't sound so good-but for the car it works.The sound system in my new car is a JBL Greenedge system that can rival some home systems for sound quality.It has an 11 channel digital amp that is rated to 825W.Playing my Auditorium Organ" and other CDs of the Atlantic City Convention organs never sounded so good.The system even reproduced the test cut of the 64' Diaphone stop-not live volume but reproduced it somewhat-better than other typical car systems.The system has a 12" subwoofer in the back.Will take this factory system over any aftermarket one any day.The system in the car was DESIGNED for it unlike aftermarket which have to fit ANY car.This old guy still uses his CDs,DVDs,and BluRays.Don't know how that other stuff works-too much trouble and hassle.
