hi,

Anyone knows where to get the 997-1 pcm repair cd? Tried to upgrade to 2.1 but something went wrong and the head cd unit cannot read disks any longer.

Thanks in advance

Are you able to eject the CD you put in the PCM to do the upgrade ? The PCM has a software reset by pressing 148 on the keypad. Alternatively you can pull the fuse that powers the PCM in the fuse box and leave it out for a few minutes. The PCM update should be done only when you are sure you know what procedure is required. This means you need to interrogate the PCM first to find its current software level and what other devices software levels are on the system. Depending on the date of manufacture and options fitted , sometimes a Bose update is required or in a few cases a complete replacement of the bose amp to a newer model.
