Porsche updated the PCM/NAV with the latest software and replaced the GPS antennae. I think it worked for my drive home and then failed again.
Leading evidence: 'Replace gps antennae' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'generic screw up' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Disconnect battery' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suspected cause
Its probably the generic screw up but just in case you can get away lightly.

I would try disconnecting the battery for 5-10 minutes.

I've tried to reset the NAV, switch to German and back to English, and even tried the DVD from my Cayenne.
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.

I've seen it report 1sat but the same issue persisted even when this changed.
My 2004 996 Turbo Navigation thinks it's somewhere in NC. If I'm not mistaken I'm running PCM3 V3.
I can calculate a route but the starting point is a few states off. I've tried to reset the NAV, switch to German and back to English, and even tried the DVD from my Cayenne.
The info shows that it is getting satellite. Porsche wants $600+ to update the software. I'm looking for a DIY fix. Any direction is appreciated.
First post. Glad to be part of the club
'04 nav has some bugs. Ask me about my trip to Hilton Head. Not sure of the fix.
Oh, post pics. Your response will be better, and Tim won't have to use caps lock.
I'm a little weary about doing this. What will I need to do once the car 'wakes up' again. I don't have the radio code. What are the risks associated with doing this?
Nav doesn't need a code that I am aware of. I have done it several times on my 04 with no issues. The computer will have to remap the fuel mixture this will sometime smooth out a rough idle.
The other thing you could do it just pull the nav fuse.
Searayray,
Even thought you didn't post pics (more on this later)
I will help you out. The '03 and '04 cars have the radio code programmed in the the computer so if unplug the battery,
your radio will work
correctly after you reconnect the battery.
Also, Welcome to Rennlist and congrats on getting yout 996. However, it is customary for Newbies to tell us a little about their car and to post pics of it. So consider this next senrence your "Newbie Initiation!"
Come on Newbie, post the @#$%^&* pics!
searay - welcome
please forgive me for taking your car on a mental trip to Hilton Head... you can resume control now... sorry
in the event you are still in german mode
Willkommen Bitte vergib mir nehmen Sie Ihr Auto auf eine mentale Reise nach Hilton Head ... Sie k�nnen jetzt wieder die Kontrolle ... Entschuldigung
If it is always staying in that region I imagine it isn't interference getting into the wirings. I've read some warnings about after market installs of stuff causing problems. Any chance the antenna is obstrucred or disconnected? Its probably the generic screw up but just in case you can get away lightly.
Thanks for the input guys. I promise to upload pictures of my cars in the coming days. I pulled the negative for a minute and the PCM asked me for the NAV DVD...took a minute to load and...
same thing
. I drove out of my garage and drove a few minutes in hopes the NAV would find the location, but no luck. I don't mind doing some more troubleshooting. Where can I find the GPS antenna?
Also, yea I have the right region disc in, but I don't think u sing the wrong one would confuse the car about its current location. No aftermarket stuff in the car. If I go to info the car reports 0sat and GPS 1d. I've seen it report 1sat but the same issue persisted even when this changed.
Hey Chris,
Porsche updated the PCM/NAV with the latest software and replaced the GPS antennae. I think it worked for my drive home and then failed again.
Porsche then suggested that the entire PCM be replaced at the tune of several thousand.
My advice - replace it with an updated after market head unit and sell the old PCM on ebay for parts.
