I thought PCM is supposed to pick up date/time signal from GPS. I drove about 1 hr today but time is not updated.

 

A few weeks back, mine somehow got set one hour off the correct time. It can be corrected manually by going into Options (or similar )on the TFT Screen and finding the clock there.

 

I just got an email from PCNA with instructions on changing time. Never got anything like that from another manufacturer. Here is the contents of the email:

Updating Daylight Saving Time in your Cayenne, Panamera, new Boxster (981), and new 911 Carrera (991) models

This Saturday night into Sunday, November 4th, Daylight Saving Time concludes in most of the US and you will need to move your clocks "back" one hour. To help you do so, we've provided some quick instructions below as well as a link to a short video depicting the process for your Porsche.

To watch the instructional video click here: Setting Date and Time.

You can always contact your local Porsche dealer or call 1-800-PORSCHE option 3 with any questions should you need assistance. For more helpful information on how to operate your Porsche vehicle, please visit www.porscheownersmanuals.com from your smart phone or computer.

Wishing you many happy miles in your Porsche.

konakai and dhill911, thx for the tip.

 

Can you believe that!!! The Clock changes automatically on my '08 Acura TL but Porsche, in 2012, can't include the technology to do the same,,,what a shock.

 

My 2012 BMW 650 Cab didn't have the technology to change either. Had to do it manually yesterday.

I'm glad it doesn't.

A few years ago they changed the standard for when daylight savings time is in effect. If they had programmed it to automatically change then the PCM would have needed a software update to change the schedule for the time change or else you wind up in a tug of war with the computer.

If the update didn't come then we would wind up having to change it 4 times a year. Twice on the right days and twice setting it back where it belongs when it changes it itself on the wrong days.

I know they don't make changes like this often, but it's my preference to be in control.

Also, aren't there some areas of the US that don't observe daylight savings time (like Arizona)?

 

In Canada we have at least on Province that doesn't have Dailight saving time also.

So if I drove cross country I'd have to manually change the time in every timezone,,,,, unbelievable for a car of this caliber.

 

So I was trying to get the system to display the correct time and it kept changing it back every time I would re-start the car. Then I see the thing about time zones. OK, why is it greyed out? The PCM has been on for a while, what gives? Oh, I have to leave my garage so the car can receive a signal to allow me to change from Eastern time to Central time. OK, so how did it change to Eastern time in the first place since it was accurate prior to needing to change it?? Who knows. And yes, does that mean if you travel thru different time zones you have to reset the zone each time? My $10 electronic clock does better than that!!

 

Guys it's a car not a cell phone ...lol

 

Back atcha-- actually my car is a cell phone, it is an entertainment center, it is a view to the clouds, it is a mobile storage device, and, yes, it is also driving wonder. I guess I just expect all this stuff that I pay for to work. Let's see now, multiple recall "campaigns", multiple visits because Germany is on holiday and no one else on the planet is authorized to give out the secret codes, a pcm that still glitches, and a clock that can't be set correctly unless it sees a satellite. Sheesh...but do I want to go back to "it's a car"...no a/c, no driver/passenger heater, no radio, no gps, no deviated stitching...not on your life!

 

Oops, sorry to hear about your troubles my friend. I tried to be funny , obviously it didnt work.

I agree, these issues must be addressed for the amount of money we pay for it!
