Suggestion
There apparantly was a hardware change made for 2002 that enabled more data, but is not compatible with the PCM1 systems prior to 2002.

Suggestion · Original poster
But I also need to get updated discs -- the newest set I have is from 2000.

I am, and have been, using 2003.1 in my PCM 1 unit for a couple of months now.

I have a 99 Boxster w/PCM1 and could use a copy of the SE CD if anyone has one.
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.

My 1999 C4 is getting older, and I'm starting to get frustrated. I have a PCM unit. I love the navigation system.
But AM radio reception
stinks
. It's horrible. Either there's irregular popping, or swirling and shreiking whistles. I expect there's a grounding problem, but what isn't grounded correctly? The PCM unit itself? The in-trunk amplifier box?
Is there a TSB about this problem? I seem to remember it being common back when I bought my car, but never got my dealer to pay attention to me.
My original CDC-3 died on me. I replaced it with a Becker Silverstone 7860, and that one died within six months. I found a used CDC-3, and it seems to be working ... for now.
If I can fix the AM interference issue and the CDC-3 keeps working, I guess I'll keep the PSM I system.
But I also need to get updated discs -- the newest set I have is from 2000. Does anyone know if NavTech is still producing these, and how much they cost?
But say things don't work out. I've read some posts here from folks who have installed other systems; I guess I would go with a Kenwood DDX7017 and the Sirius and navigation add-ons. Can anyone suggest a better system? Does this rig lock me into Sirius, or can I get XM?
TSB:
9005 Suppressor Kit for AM Reception Noise Mar 25, 1999
Get updates (if available) from
NAVTEQ
. The website says there are no new updates however.
There are a lot of cool replacement options. Alpine and Kenwood have some awesome units. But, I like the temp/mileage/speed gong/other data integrated in the PCM.
Call and talk to Navteq. Approximately two weeks ago, I bought the newest version of the CDs, which is labeled 2003.1 In my experience, the website is never, ever correct.
W00t!!1! Thanks! I'll see if it has ever been applied to my car.
I've already gone through the NavTech site. They say there's "no new updates". But how can they possibly know which version I
currently
have?
It's neat, and having the HVAC controls is nice, too. Thing is, these are redundant to the HVAC control panel. My car also has the BC, so I get the speed chime, consumption, and temperature up there, too.
Don't bother going to the Navteq site ever. It stinks. Rather, pull out your CD tonight. Unless it is 2003.1, you have an out of date CD. Call Navteq, insist that there is an update available, and order it.
BTW, they say that there will be no new updates, ever, for the PCM 1 . . . Bastards . . .
I just called them also and they denied that 2003.1 would work on PCM 1. They said only the 2001 version would work. I'm having second thoughts about retro fiting my 99. Are there any other issues that I need to be concerned about before I undertake this?
Call back and talk to a different service representative. I am, and have been, using 2003.1 in my PCM 1 unit for a couple of months now. As far as I know, PCM 1 is PCM 1, and there is no reason why it would work on mine but not yours.
TD, Are you sure its 2003.1, and if it is that you don't have PCMII? I just ordered the latest disks for my 2000 with PCM 1 and they sent me 7 disks labeled 2001.1. Do you have 7 disks or fewer for the whole country?
I could not be more positive that all the new disks I just bought from Navteq say 2003.1, and I am absolutely positive that I have PCM 1. I bought the disks for the entire country, but I cannot remember how many there are. Trying to get accurate information out of Navteq is nearly impossible, and I have had luck simply by being polite but extremely persistent.
Interesting. This post from Renntech says that the most recent PCM1 disks (7 disks) are 2001.1 and the most recent PCM 2 disks (2 disks) are 2003.1. I did not think the 2003.1 disks would work with PCM 1, since the hardware is from a different manufacturer than PCM 2. I'd like to try the newer disks with my system so I could exchange the 7 older disks I just bought from Navteq.

Now, let me add to the confusion a little more. My disks that say 2003.1 are definitely more than two. When you asked how many I had, I didn't really remember, but it is somewhere between 5 and 7. I promise you that I am not making this up . . .
The 2003.1 disks work just fine, and IIRC they have additional features (e.g., more information regarding POIs).
On the way in to work, I snapped a few pictures of my PCM1 and the 2003.1 disks. I will post them later. The disk in my PCM1 right now says "Disk 6: Mid Atlantic . . . . 2003.1" So, there are at least 6 disks (maybe 7, I don't know), they are very clearly printed as 2003.1, and they work in my PCM1.
Who is more trustworthy, (1) Navteq, (2) Porsche, or (3) fellow rennlisters?
Don't worry, I will post photographic proof later today or tomorrow . . .
Just got off the phone with Navtech. There are two "newest" versions of PCM1 cds. 2001.1 from Feb '01 is for pre-2002 MY. 2003.1 from Feb '03 is for 2002 MY. There apparantly was a hardware change made for 2002 that enabled more data, but is not compatible with the PCM1 systems prior to 2002. The 2003.1 disks won't work in pre-2002 cars.
I have a 99 Boxster w/PCM1 and could use a copy of the SE CD if anyone has one. Don't really care how old it is, just want something to make the screen go from brown to blue :-) I have a NE and mid-oh CD I can offer in trade.
FYI, I just put the Kenwood DDX-7015 in my 911 without the nav piece, and love it. I have a music keg and sirius and it does just what I want it to. Only gripe is that the Sirius/Keg display is still only one line. It should have been able to accomodate a 4 line display that showed artist/title/station/etc with one view.
Talked to my dealer yesterday about upgrading the PCM 1 firmware in my MY2000 for the 2003.1 disks. He says it can't be done. Guess I should have him talk to R1rb's dealer.
