I THINK U can play UR CD's through UR audio system in UR vehicle by using the optional car audio jack that must have come with the portable CD Player. Hope I''m right! I THINK IT IS A GREAT SHAME THAT AUTOMOBILE MANUFACTURERS ARE LEAVING CD PLAYERS OUT OF NEW VEHICLES!!!!!
It has a "line out" feature that I used with an insignis 3.5 mm audio cable to connect it to my RAV 4 (car) AUX jack on the car's dash. It then played nicely thru the car's speakers; I listened to "books on CD" while traveling out of state recently; it was great!
The unit has a temporary stop when you push stop but it lasts only 60 seconds before it shuts the system off to conserve batteries. So, your answer is yes but only for 60 seconds.
