There's a connector under the scuttle panel which hadn't been reconnected correctly.
Leading evidence: 'Reconnect correctly' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check connection' (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.

Had this after my windscreen was replaced on my 987.

I have reset the PCM and tried turning the car on/off but to no avail.

If you get funny GPS results always worth checking your local NOTAMs to see if anyone is playing !
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.

They resolved the problem but I think it may have involved the removal of the rear bumper.
PH'ers,
I have a 2018 718 Cayman S and on my last two trips noted the Maps function is showing me being 2/3 towns over. Weirdly enough, if I enter a route into the SatNav it also shows the route starting from the wrong location.
I have reset the PCM and tried turning the car on/off but to no avail. Have read online about a 148 reset on 991s but not sure what it refers to.
Any ideas? Would like to avoid disconnecting the battery if possible to avoid other gremlins.
Thanks in advance!
Battery dieconnection doesn't cause gremlins in Porsches in my experience - I'd give it a try. I have experienced the issue you describe, but it corrected itself after the car was driven for a mile or two. How long has this persisted? Do you live in a city will lots of tall buildings?

Last drive I did was only a couple of miles so might take it for a blast on the motorway. Last journey was 2 weeks ago (its a crime i dont drive it more).
Live in a semi rural area so can imagine the signal can get bad but never experienced it before.
One thought is whether i drive to the location it says im in and whether that will cause it to reset
Have you set "home" as a location in the sat nav? My 2021 718 Cayman defaulted to Porsche Bolton as a start point for most journeys when new, but I seem to recall it got better after I told it where it lived. The MyPorsche app fared slightly less well, frequently telling me the car was in a field just off the A56 with the driver's door unlocked, and both front windows open, when I was away on business. It somehow returned to my locked workshop without accruing additional miles before I got home every time.
The latter has improved a little with the current Porsches in the workshop, but the app still chooses to raise my pulse over false claims of unlocked doors to this day.

I had the same issue on my 2018 Boxster S - the satnav sometimes thought I was one or two streets over from where I actually was. This was an intermittent fault, sometimes it was entirely lost.
The car went into the OPC who diagnosed it as a wiring connection issue to the satnav antenna. They resolved the problem but I think it may have involved the removal of the rear bumper.
It seems fine at the moment, they said that if the issue reoccurred they would need to replace the satnav antenna.
Had this after my windscreen was replaced on my 987. There's a connector under the scuttle panel which hadn't been reconnected correctly. I'm making an assumption that it's probably similar on a 718, and have you have a screen replaced, or the scuttle panel removed for any reason?
Thanks for all the suggestions.
Oddly the issue seems to have fixed itself after a 30~ drive through a couple of towns. Assuming it was a satellite connection issue vs hardware.

987 and 997 GPS module is under the scuttle, yes; later models it's on the windscreen behind a cowl on the mirror.
This is a source reference. Confirm exact model applicability in the original material.
