I recently purchased a CTT with PCM 2.1 (DVD) and have a 10.2004 DVD. I would like to update the system and have read so many posts with different experiences and recommendations. I recently saw this LINK

Am I able to purchase this and update? I know I am running PCM2.1A currently.

Also, I noticed some information about the Amplifier becoming 'JUNKED' during the update/upgrade. Any more information on this?

All your help is appreciated.

There are several post on the forum related to your topic. Yes you can update your PCM but you'll also need to update the PCM operating software also. I believe the newest maps are only up to 2008 so I don't consider it a useful upgrade. If the voltage drops low during the update procedure you can damage the PCM.
