EU/UK: Ongoing navigation issues

[dutchdriver]

Recently brought my CT 2022 in with this issue. Dealership updated PCM to 3885 but told me this wouldn't fix the navi issues yet - and confirmed on the drive home as the navi crashed.

However - yesterday had to make a long trip and decided to test again (with charging planner enabled), this time no issues at all. Curiously, I checked whether there had been any new software updates installed, and noticed my Navigation Pack version now says 2026.02. Could this be the fix?

But if I do as usual, plan my stops with ABRP and enter the next stop as destination and as a charger, the car will precondition and give me the % at that stop?

If it's the case and it never crash anymore, I could live with this.

Are you using ABRP with an OBD adapter?

Are you using ABRP with an OBD adapter?

Yes, I have ABRP with OBP but it's not always plugged and I have the loink with Porsche and tronity as well.
But I nearly always plan in advance in ABRP and keep a copy of the planned trip on my phone even for the long 1000 km trips that I do 4 times a year.
I'm like that, I like to plan in advance and know what are my options if something happens.
This way, I often stop at a DC charger with only 2% and charge until 70% in 15 min and drive fast to the next one.

I will take my car at the dealer tomorrow and will directly check with a long drive and test multiple options to try to crash the system.

I don't seem to have this issue, i used it yesterday without any problem in my 73GTS. I guess its not everyone then?

It affects all cars; but it’s not that noticible if you don’t drive longer trips or relay on public charging .

I also don’t get it on repeated routes, that I drive a lot; say to work and back.

For me the PCM still crashes even with the charging planner off, less often - like every 30 mins - but it still crashes . However the turn by turn navigation doesn’t freeze anymore, so at least that’s a thing

No, that’s just the map data version (new roads added, old roads removed, etc.). The problem is within the navigation app itself.

I thought the same - Last week I had a trip where it worked flawlessly. But it went back to regular reboots and being useless just a few days later.

It was a 3 hour drive with a charge planned.
I will stick to Zap Map anyway as its better than the PMC and no idea of the battery setting advantages etc.

Update on January 21, 2026:

It’s been six months and more since I first noticed this issue. Here’s what we’ve learned from this thread so far:

- It appears to be a problem exclusive to Western Europe and the UK.
- It seems to be caused by the OTA update for the Battery Management System (BMS).
- Turning off Charging Planning is a temporary solution.
- Skoda and Audi forums are describing the same issues starting at the same time as this thread.
- Dealers and Porsche are clueless. Multiple small software patches have been applied, but none of them have been fixed.
- Right now the plan is to replace the PCM units. The units are back ordered and have an expected delivery time of 2 months
- You can request a refund for Porsche Connect. Contact Porsche Smart Mobility. Contact details are listed in the My Porsche section and vary by country. I received a refund for six months.

Hi everyone!

I did a 2-day road trip and ran into a few strange issues. Most were temporarily fixed with the two-finger reset, but I’d really like to understand what’s going on and see if others have similar experiences—or better, solutions.

I’m open to the possibility that I’m doing something wrong or making incorrect assumptions, so feel free to correct me. This isn’t meant as another rant about bad software—I genuinely want to focus on solutions. Here’s what I encountered:

1. Turn-by-turn navigation freezes
   About every 30 minutes, the turn-by-turn instructions would freeze for around 3 minutes. This caused me to miss exits and take wrong turns at roundabouts. This never used to happen—any idea what’s changed?
2. Navigation app crashes
   I use the PCM navigation with Porsche Charging Planner and have PIRM. About every two hours, the entire navigation app crashes—showing only a spinner and then restarting after a few minutes. Each time, I had to re-enter my destination. My trip was about 2000 km, and I noticed the crashes became less frequent the closer I got to my destination. Could the long distance be a factor?
3. Charging stop timeline freezes
   While navigating, the vertical timeline showing charging stops and traffic incidents would sometimes freeze. For example, it showed the next stop as 150 km away while I was actually only 4 km from it. This caused unnecessary stress, especially when the displayed range seemed too low to reach the stop. Re-entering the destination didn’t help—only a two-finger reset resolved it.
4. Charger availability indicators are inconsistent
   Sometimes the system shows live availability of chargers; other times, it disappears completely without explanation. I couldn't figure out a pattern. The two-finger reset doesn’t seem to bring the data back either. Does anyone know what causes this?
5. Charging plan recalculates unnecessarily
   Upon arriving at a planned charger and starting the charging session, the system sometimes immediately recalculates and directs me to leave and head to the next charging stop—even though I’m already charging at the station it previously indicated. Why would it do that?

Would really appreciate it if others could share their experiences or solutions. Thanks in advance!

Cheers Jasper

Thank you for the update!

My PCM is pretty much unusable at this point. Drove for a hour the other day and it rebooted or froze three times requiring restarting or just waiting for it to crash and re-enter the destination. Once I had to stop and wait but now I try and keep the next few turns in my head.

I've got skiing coming up in a week or two and definitely don't fancy a long trip with this nonsense of a satnav and charge planning.

Interesting to hear that they will refund connectivity and it's related to the BMS updates.

So now they'll renew the whole head unit? Does it have to be raised as a warranty issue or will they replace it anyway?

Many thanks!

Doubt they will replace the PCM, this appears to be clearer to more Porsche Centres now despite some of them having gone down that route already.

I picked mine up from my local centre today after the 12v campaign and 3885 update and they have been upfront that 3885 isn’t the fix for the charge planner related crashing. They repeated what many people have been told, the solution is coming in a few months, likely June.

I used the newly updated nav and planner on the 30km drive home, it didn’t crash, but instead reminded me that it is actually quite a nice system when it works. I use CarPlay day to day, but the native system does looks right on the PCM and the integration with the binnacle feels like it should to me.

I’ll monitor it and when it starts behaving badly again I’ll be back onto them to talk about some compensation for the already high charge for Porsche Connect.

Car felt fantastic after riding around in a Cayenne Hybrid for over a week, all is forgiven for now.

I followed up my previous mail to my OPC, which confirmed that the 3885 update had failed, - telling them that other UK OPCs had been informed by PAG that an update was supposedly on the way to fix the Nav (eventually - possibly June)....

They just replied telling me that they were not aware of any planned software update - but thanked me for the info, and said they would notify me when it was ready to be installed.

So not every OPC has been informed yet.

PAG and SmartMobility UK communications are obviously dreadful...

 

[Jasper4S]

Note that was the update from januari. Last weeks we've learned it is not the final solution. It has been one of the things they tried.

 

[Jasper4S]

I’ve updated the original post with new information, including safety risks and the reimbursement I’ll receive from Porsche Nederland (the importer), which is approximately €1250. Confirmed over phone by my OPC. It's not much, but it was the first time I felt some acknowledgment.

I did not receive it yet, so I hope I don't jinx it. My advice, ask for at least the same; a reinbursement for Innodrive and PIRM as those FODs are useless right now. I did receive 6 months Porsche Connect free of charge. Will ask for more in a couple of months of course.

I want to share a strange experience on a round trip I just did: about 350km each way, requiring one charging stop.

I decided not to use the charging planner, to avoid NAV crashes. It was off both ways, I checked that several times...

Indeed, NAV did not crash a single time on both trips. But the strange thing is that:

- when adding manually the charging stops as a waypoint (since charging planner is off), NAV interprets them as charging stops

- and it does precondition the battery

Both times, heater started as "normal" and battery temp. was right on for the stop. With an average of more than 180kWh from 8 to 82%

I'll soon do a longer trip (3 charging stops expected) and check if can get the same to happen...

 

[okkotonushi]

That’s how i do it as well
