PCM - Target vs Actual

[stallion.ru]

Hello Gentlemen,

early '05 997 C2. Multimedia CDs arrived - but having browsed through the forums I am still concerned - my Software versions is 1.0, and the BOSE amp info shows the following:

Unit: Amplifier

Target: 00016400 / 3531

Actual: 00017500 / 3504

Entered: Yes

Found: Yes

So - what is the actual Amp version installed - 16400 or 17500? And if it is 16400 - I guess upgrading the PCM software will brick it?

Thanks for any help,

Regards from Moscow,

Vladimir

Vladimir,

I believe the 'Actual' is what the level query found. The 'Target' is what it expected based on your PCM Software Level.

I suggest you go to this thread http://www.renntech.org/forums/index.php?s...p;hl=NAV+update and give it a good read. It might answer or help you w/ your planned update. If you have an early bulid 2005 997 I suspect the Bose Amp was replaced at some time since it's at the 00017500 level. You might want to check the Bose Amp part number to confirm this.

Good Luck!

This might help!

According to the "PCM2.1 and BOSE Amplifier spare parts requirements" before updating to Model Level A, you must first check to see if you have the correct Bose amplifier.

It states any Bose amp having part number 997.645.333.04 or 997.645.333.05 must be replaced with 997.645.334.22 or newer.

Thanks AP 997S!

Actually the thread you mentioned is the one that stopped me from immediate upgrade...anyway - 2 questions remain:

- how do I find out the amp PN - the amp is located at the bottom of the trunk if I am wright - but the only things I can see without replacing it is the radiator and cooler...

- as for the CDs - I guess I shall start with CD2 first?

Thanks again,

Vladimir

The Bose amp is located as you mentioned in the trunk. Just remove the panel that covers the tools and the amp is mounted on the rear vertical wall. Two (2) captive plastic fasteners hold the cover in place.

You might be able to spot the amp label that has the part number info but I doubt it. The amp is secured on each end with a sliding fastener. Just remove the connector and slide the fasteners to remove the amp. Once out you'll spot the part number data.

Hope this helps.

Hello AP 997S - thanks again for your help - everything went just fine today - all softwares updated (3.0 now), sounds great - Amp Actual really reflects what the MOST test of the device returns.

Have a good day!

Where do you guys get the update disks? what are the main advantages of upgrading to 3.0?

Google and torrent did that for me...as for the advantage - I have replaced CDC with Mobridge box which allows me to use my iPod. With SW ver 1 - any time I turn on the ignition I would hear a whistling sound from Mobridge, which will not go until I switch to FM and back to CDC. No more problems with that now with SW 3.0

But fom most of us - ability to use the latest Nav disks is the reason.

Vladimir

Be a little careful with torrent downloads of the update software. They do not contain any instructions on using the ISO imges , if the file is corrupt you can turn the PCM into a brick. There is no reset for the PCM if the software update is corrupted or fails , even your porsche agent cannot help. The update will only allow your PCM to overcome compatability isues with aftermarket devices such as the mobridge , and the ability to use newer maps than 2004. There is a lot of fiction about the update enabling Mp3 playback, this is rubbish , it doesn't as the hardware in the PCM doesnt support Mp3 playback on pre MY 2006 cars.

Thanks Berty, I was lucky enough to have everything settled up/ The reason for upgrade was - exactly right - compatibility issues with Mobridge - now it all works as it was supposed to.

All the best from Moscow!
