So I have a 2004 Pontiac grand am and it doesn't have a jack to plug in an aux cord and it is not blue tooth either. It is just a simple radio and does not have a tape thing either. My old car had a tape type thing with a cord connected and I used that, but this car does not. My friend told me about this Bluetooth charger thing that plays your music out of your car speakers when you plug it into your phone. Does this work? It seems like too simple to work but I haven't tried it. If it doesn't work, how else can I make it so I can listen to my own music? Thanks!
