Question about Bose 3 2 1 GSX System
I was using the fm and the audio cord came out. While attempting to plug the cord back in I turned the unit on it's side and the stereo turned off. Now it will not turn on by the remote or the on / off button. When I power the unit down and repower it displays the 321 on the screen but then nothing after that.
Your have to open the system removing the six screws on the bottom. Once the cover is off you might want to remove the am/fm connetion to give your self more room. You just unplug it from the board by gently pulling on the white connecting plastic and not the wire. Pull the am/fm board toward the front a bit and lift up. You shold see three shinny metal wires per say. and the one you want to check is the one that looks like it's connecting straight into the display screen. Notice two seem to connect towards the front. You want the one that is straight forward. This was the connection that had come undone on my system and was causing the no power up just the "BOSE 3-2-1" message.

o Bose radio uses a standard nine-volt battery that serves as a backup for the memory and alarm when it's unplugged or when the power is off. It will power these functions for up to three days. Using the radio without the battery won't damage it, but the memory won't be backed up. The battery does not provide enough power for normal operation, including the lighted display.
To install a battery, turn the radio over. Push on the arrow on the battery chamber cover and move it aside. Match the terminals on the battery with their opposites inside the chamber, and push the battery securely into place. Close the cover and return the radio to an upright position.
Connect the power cord to the jack on the back of the radio. The flat side of the connector must line up with the flat side of the jack. Since the power cord contains the FM antenna, uncoil the cord for the best reception. Plug the power cord into a standard electrical outlet.
An FM cable connector is on the back of the radio. Contact your cable company for help in setting up your connection. When you set it up, be sure to use a splitter that separates the FM signal from the TV signal so that the TV signal won't be transmitted to your radio.
If your remote is slotted on the back, press the tip of a pen into the opening and push the battery chamber cover to the side. If there's no slot, push the tab to one side with your finger and open the chamber cover. Use only a lithium battery size CR 2032 or DL 2032. Place the battery into the chamber with the plus sign face-up. Push the chamber cover closed and it will lock.
