Topic: Alero radio codes

[demanufactured]

My radio is locked on a 99 alero I bought used last year and I dont have a code for it.  I took it to the dealer and they tried what they thought was the code but it didnt unlock it.  Any ideas???

Demanufactured Welcome to the Forum. I would get on the ph. and talk to GM's Hotline as they have more info available then the Dealers do quite often. They should be able to direct you to the right people who will have this knowledge you need.

This is long but contains the information you are looking for, reformat and print this out and bring it to your local GM tech or whoever needs to perform the task. I have bolded the section that explains why your radio is displaying this

Radio Setup
For the DE 100 series radio, complete the following procedure, using a scan tool, in order to properly set up communication:

At the Main Menu screen, select: Diagnostics.  
At the Vehicle Identification screen, select the following options:  
(1) 2001 (Model Year)  
Passenger Car  
At the System Selection Menu screen, select: Body.  
At the Vehicle Identification screen, select the N (Platform type).  
At the Body screen, select: Radio.  
At the Radio screen, select: Special Functions.  
At the Special Functions screen, select: Radio Setup.  
At the Radio Setup screen, press ENTER (The following test will set up a new or existing radio).  
Select one of the following Regular Production Options (RPO) using the arrow keys and press ENTER.  
UM6  
U1Q + UL2  
U1P + U85  
U1Q + U85  
Select one of the following options:  
USA/Canada  
Export  
Press the ENTER key.  
Verify that the scan tool displays "Test in Progress."  
Verify that the scan tool displays "Test Completed Successfully."  
Press EXIT on the scan tool.  

Important
The radio set up will configure the following systems:

LEARN VIN  
Diagnostic Trouble Codes  
Class 2 Radio Messages  
Country Code  
Chime Volume  
Chime Level  
12/24 Hour Clock  
Without learning the VIN, the radio will display a locked message (LOC).

The radio setup procedure will also clear the following messages:

CAL  
CAL ERR  
CALIBRATE  

Cycle the ignition.  
Radio Tuner Calibration
In order to calibrate the radio, begin at the Special Functions screen. Repeat step 1 through step 7 of the Radio Setup, if needed.

At the Special Functions screen, select F1: Set Options.  
At the Set Options screen, select F1: Tuner Setting.  

Important
The F0: Country Code option does not contain a submenu. Country Code sets the point of sale, or origin, in the radio in order to calibrate the tuner for the country that the vehicle will be used in.

Holy bananas, Run.  Did you have that information just laying around on your coffee table, waiting for the right moment?  

Good catch.

Thanks folks, I have access to an elecronic GM service manual, comes in real handy. Of course, I would not know how to do this radio setup thingie, but sometimes having access to information can help.

[barrie1]

Now thats a handy item to have access to, wish I did myself as I generally use one of my many service manuels or the phone to a few inside no's in Dealerships.
