Hi MBZ81,
You need to check two things. 1) make sure the Tuner Pack in the trunk is plugged in properly. If you had a CD changer and it was disconnected or removed the cables may not be completing the circuit with the Head unit. 2) Check to see if you have power to the Tuner Pack. There is a fuse in the back of the Tuner Pack. Make sure it is not blown and that it has 12 volts when the system is on. Let me know how you make out. If you need more info please contact me via my Web site at: www.lajollaaudiorepair.com
