    I finally was able to get in touch with the mfg (Pioneer) to see about getting the code. He said there is no code! He said a long time ago they used to use a security code but not anymore. Who knew?
    It only took me a half day to pull that radio and now I have all these extra screws left over.
    Well, I need to recheck the obvious once again...maybe pull all the fuses and check with a VOM?

    Ok...I tried everything suggested here. Nothing has worked yet.
    I pulled the radio unit again today. Check for incoming dc voltage.
    None. I checked the fuse for the radion in the dash panel. Voltage at fuse. I checked the fuse in the back of the pioneer unit. Good.
    I check every fuse under the engine hood also. All good.

    I know that the hot wire from the Avalon's wiring harness is white
    (although there appear to be an occassional speckle of silver also).

    So somewhere between the radio fuse and the hot wire going to the radio is a problem. What could it be? I have a Haynes repair manual but can't seem to find that white wire going to the radio.

    Any other ideas, all?

    did you at any time disconnect the battery and leave face plate on from pioneer web site this is updated technology

    disconnecting the battery with face plate on should reset itself

    i was told the face plate is the security feature built in

Hi Elimo

Two pics as the manual had the paragraph separated. This is for DEH 2500 only. Let me know if you want the 1500 as well.
