Hello everybody! I just got Escalade 2009 model. In the mean time I've found problems with CD changer playing mp3 music. It can play only 20 -30 first songs from CD and it does not "read" the rest. CD is perfectly working in the other car. May be someone is familiar with this problem? Also there is no USB port in the car , have anyone installed it somehow or replaced audio system to a newer one?
