LAPower (Mr 12 Volt) BT adapter. Long thread about this on Rennlist 997 forum.
My date is incorrect and does not display on the main PCM display now. The time and timezone are correct at least. I've tried different date formats too. If I have time I may run down to my local indy that has PIWIS and see if that helps the issue. Its a small annoyance. Porsche could do something about this as it appears to be a programming bug. There is a PCM update disk set being sold by a vendor and they have a 2015/2016 maps update. I may try that and see if that corrects the issue if nothing else fixes it.
It did have a newer battery prior to purchase. I did disconnect the battery to do the Alt-Starter battery cable change but that was back in Sept. The date was displaying correctly until new years day. Maybe I will take it to my local indy as he has PIWIS and see if he can do a reset.
Very interesting. My PCM is at Rev B but using older maps disk. I will change the date format and see if anything changes. Keep us posted if the date sticks
Yep - You are missing the date in the Main display. I called my local Pcar dealer but I got the usual bring it in and we can look into it - for a fee or course. Anyone have a PCNA contact as I think this is a weird problem (bug) , albeit small, in the grand scheme of things. Im hearing more people report this across other Porsche forums.
Out of curiosity do you have a date displayed on the Main PCM screen or is it missing? Mine still says 01/09/2000 and is not on the Main screen any longer.

This is being reported on other forums for the 997 and early Cayenne's and I'm in the same boat along with a coworker. The date display on the PCM is blank while all other settings are correct. Ive done the 1,4,8 reboot and pulled the fuses etc. I have 8-11 Sats locked in and the map follows me correctly. This just started a few days after the new year. I suspect there is a firmware bug in the PCM with the coming 2019 GPS Week Rollover. I wonder if a PCM Nav update to the latest SW & maps (2015/2016) works around this?

I'm planning on doing this replacement with the excellent DIY documentation found here. However, my 997 is a Tip - is there anything significantly different in performing this from a MT before I get started? I have not found anything specific at this point other than the correct part # for Tip's Thanks
