"Software optimization" and "increased robustness", not bug/problem fixes.

Porsche never has problems or bugs, they are perfect like that

So is this the long awaited update to fix the Porsche navigation system and stop it from crashing? Only way mine works is if I switch off charge planning in the nav settings.

Does this 'fix' that? Also, (forgive me if I've missed it) is it an OTA fix which will be pushed out or does it require a visit to the dealer?

If you read the full linked TSB the remedy steps listed are by dealer service.

@Tango22 I can confirm this is the fix.

Thanks for the replies, both

I wonder, is this something we will need to go in and ask for or will OPC's contact us to bring the car in for the fix to be performed?

Think I'll give my OPC a call on Monday.

Think you need to initiate @Tango22 complaining about nav crashing

You may be aware but there is an enormous thread
