As a matter of interest, what it the PCM Software Version number, and what version of the map disk are you trying to run?

PCM software version is 04035AD1 / 0304

What map version are you trying to run?

I have the updates if you need them. I think you may also need the Level C update, depending on your map version.

ps map version is 04.2005 Europe

Firstly, thanks to everyone for your suggestions. After tinkering some more I have definitely drawn the same conclusion as both hahnmgh63 and Richard Hamilton. The navigation is actually working fine. I can enter addresses, i will get voice directions, and the dash control updates with where i should be going. It's actually only the map screen which seems to be stuck. I do still get the "incompatible nav software" message so I'm optimistic that a software update will fix my issues.

Richard you mentioned that you had the discs that i need in order to run the update. How can i contact you privately in order to arrange a visit and or payment for a copy? Please advise and i will get in touch this weekend.

Thanks again everyone.

Do you think that update should be all i need then and that my existing nav DVD should work as normal thereafter?

Guys i have a real head scratching issue that i would love to resolve.

I recently purchased a PCM2.1 BE 6654 (7L5.035.191H) unit from eBay as my unit which came with the car (Cayenne S 2005) was a PCM2.1 BE6663 (7L5.035.192A) and it had completely died beyond repair.

The new 6654 unit works perfectly well but there are two errors on the new device. One at start-up which says "amplifier not available" (even though i have sound) and one when i try and use the navigation system which says "Incompatible Navigation Software". The maps just hang on a single screen and are useless.

Are you able to assist with the above? As the new unit works it sounds as though i simply need to upgrade and update the software but this sounds like a confusing subject. If you can help out or provide me with any discs it would be greatly appreciated. For your further information, the software of the unit currently reads as follows:

Unit: Amplifier

Target: 00012118 / 3139

Like i say, I am basically trying to resolve the amplifier error message (the amp works fine remember as i have perfect sound) and the navigation issue. My Cayenne has an external DVD drive which worked with the faulty BE 6663 so not too sure if i simply need a new DVD, or a CD to pop on the head unit.

Kind Regards and Many Thanks in advance for any assistance.

Thanks for the info.

Roy, WA - you are correct. My faulty unit, the BE 6663, says "PCM2. 1E1 RDW EC: 105"

So are you saying that the unit that i have bought second hand which is a BE6654 is an older unit but should still be DVD based as it is also a 2.1? If so, would it still make use of the external DVD or would it need to be loaded into the head unit? I assume the latter as i already have a DVD in the external unit which worked alongside the faulty BE 6663. When I'm home later i will try loading the DVD from the external into the head unit out of interest.

Do you think i just need a new DVD for the BE 6654?

Appreciate the advice.

That's a very kind offer thank you. I'm taking it into a friend this weekend but will report back and arrange privately if i take you up.

My car definitely has the DVD under the LH seat. I'll try the CD based NAV disc as if that works then problem solved. Thanks for the feedback.

Good evening

I wondered if someone may be able to best advise with the following problem. I have a UK 55 plate (2005 model) Cayenne S and recently my entire PCM unit failed. Completely dead. 2 independent Porsche engineers failed to resurrect the unit. As a result i tentatively bought a new unit off of eBay and was delighted to find out that it worked almost perfectly. The only issues are an error on start-up which says "amplifier not available" and "Incompatible Navigation Software" when i try to route to a new location. Everything else works great and as normal.

I am not a Porsche expert or mechanic so would really appreciate assistance in what to do next. I assume it's a simple software upgrade but wanted to get some info form the experts on this forum on what is needed.

My old PCM that is completely dead and buried was as follows:

PCM 2

BE 6663

7L5.035.192A

The new unit which is installed and working at 90% is as follows:

PCM2

BE 6654

715.035.191H

After reading a few other posts, i have learned how to check the current software version in my car so i have also attached the main screen to this message. As you can see from the picture from the main screen there are alerts next to the amp, cd changer, and phone. The versions for each group are as follows:

Unit: Amplifier

Target: 00012118 / 3139

Actual: -------- / ---------

Entered: Yes

Found: No

Unit: CD Changer

Target: C32 / 2702

Actual: C38 / 3003

Unit: Navigation System

Unit: Phone

Target: 0002.22R / 1803

Actual: 05034B54 / 0305

Entered: Yes

I have omitted the PCM and System Software sections as they appeared to be in order. Based on all of the above information would anyone be able to tell me what i need to do in order to fix the two errors mentioned at the start of the post:

1.) "amplifier not available"

2.) "Incompatible Navigation Software"

Many Thanks for all assistance in advance
