It is perfectly safe to use the PCM2.0 V3 update disk in a 996 with Bose.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

7 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Recently purchased a 996 C2 which has PCM and Bose audio ... it has its original map disc and I’d like to upgrade so have been doing some reading, and have ordered a PCM update disk to take the firmware to V3.0 and a recent map disk. However, I have read some conflicting information regarding upgrading PCM with BOSE and the possibility of bricking the Bose amp! Although most of the info appears to relate to the 997 and PCM2.1 Can anyone tell me whether I need to make sure I upgrade the BOSE system (how?) or will the 996 PCM2 with BOSE upgrade OK? Many thanks in advance.

POST 2Original post

Welcome Mark! It is perfectly safe to use the PCM2.0 V3 update disk in a 996 with Bose. As you say, it is only the early 9x7.1 Bose amps where you have to be careful. Just make sure the update disk supplied has part number 000.043.205.46. There is also a separate update disk for Bose to address an issue with sporadic sound failure. If you don't have such problems don't bother with it, but if you need it I have a copy.

POST 3 / ORIGINAL POSTEROriginal post

Thank you Richard. Puts my mind at rest. The map and update disc I have ordered from The Sat Navi Shop ... I don’t know what the part number for the update disc is. I expect it will be a copy so is there any way to check? I don’t appear to have any sound issues with my Bose system, but thank you for the offer, it’s very kind of you. I’ll post an update on how it goes when I get the discs through. Mark.

POST 4Original post

When you get the update disk, pop it in your computer (if you have a CD drive!) and open the file update32.inf. Check the first couple of lines read like this: [system] ReleaseVersion=3.0 AllowedDevices=6631,6632,6633,6634 I just wanted to be sure that you weren't getting a PCM2.1 update. Some sellers don't have a clue about the intricacies of the PCM updates.

POST 5 / ORIGINAL POSTEROriginal post

Ah, that’s very helpful. Many thanks indeed!

POST 6 / ORIGINAL POSTEROriginal post

I finally got around to completing the PCM2 V3 upgrade, and thanks to Richard who allayed my fears, all went to plan. Much easier and less risky than in my Range Rover! only apparent issue was the Bluetooth adapter that replaces the CD Changer ... on rebooting, the PCM claimed a fault with the CD Changer and the BT wouldn’t work, but after a system shutdown it’s all back working again. i now have up to date maps (well, 2016 dated) ... it seems a worthwhile upgrade although I cannot see any changes to look or options on the PCM itself.

POST 7Original post

Hi, does anyone have a copy of the PCM2 software version 3 they can share or the disc they no longer need. Thanks Jer
