I recently installed my old Sony CDX-GT22W (Xplod) radio in my 1999 Jeep Grand Cherokee Loredo..hoping to get the same enjoyment and conveiniance and when it was intalled in my older truck. For some reason, the TUNER setting works fine...all speakers and lights...everything..works fine. But AUX and CD have no sound. The CD player spins and displays cd and song etc. but NO SOUND. Can anyone explain if there are any specific wires of fuses I may have mis-connected?
