Speed Limit Display On PCM
Discussion
Set a destination on the sat nav today and found the speed limit displayed on the map screen on the PCM. Got to my destination with it changing for the various speeds on the route, but it disappeared for the return trip. AFAIK it’s an option on the 718. Not sure whether this was a freak occurrence or whether there is a way to set this as cant find an option to do this.
Sat Nav should pick up speed limits and display them on the map as you're driving. It only works if the map is 'centred' (press arrow in top right to centre the map on the car IIRC).
Very useful feature. I didn't want to pay the ~220 extra for the speed limit option, as this sticks a horrible great big camera in the centre of the front grill which reads speed limit signs, and looks faintly ridiculous.
The one that you get with PCM anyway seems to work just as well.

No it doesn’t stick a camera in the front grille, that’s the radar cruise control gizmo. Speed sign recognition camera is a sensor located on the inside of the windscreen, ahead of the rear view mirror.Edited by Tim bo on Monday 9th October 03:10

A ha. Well the salesman at OPC West London was entirely incorrect then. When asked what that big round thing on the grille was, he informed me it's a camera which reads speed limit signs for the PCM.Not the first time car salesmen don't know their own product in my experience.

One 981 seller with this told me it often picked up side road speed limits so gave the wrong speed anyhow. Not a good way to try and sell a car!Edited by Tim bo on Monday 9th October 03:10

I can't see it offers any meaningful advantage over what comes as standard with PCM. Ok so PCM maps may be out of date and therefore display the wrong figure, and don't take into account roadworks etc, but if the camera system gets it wrong some of the time seems like poor value (not that we aren't used to poor value with Porsche).dreamcar said:
I’ve never known the speed sign camera show a wrong speed! It also picks up temporary speed limits, for example on motorways which are nominally 70mph in SPECS road work zones where posted limit signs are 40 or 50mph it recognises them and adapts the sign recognition accordingly.
Accepting that - but is that a real advantage. You've got to be a real idiot to get caught by SPECs (since it's average rather than instant). Now if it could recognise speed camera vans that WOULD be worth paying for! bcr5784 said:

I specified it mainly for continental trips where urban & rural speed limits are not always do clearbcr5784 said:

Get Waze on your phone....it has a "social media" element so other Waze users can post speed traps etc...also has a very reliable database of fixed and avg speed cameras. The social media bit works very well for traffic too.

I've tried Waze (and pretty much everything else) and settled on using the PocketGPSWorld database for speedcams either using their App or, more commonly, via an old TomTom which I put in the compartment between the seats. Works fine all over the world (yes I know it's a bit naughty in France and Switzerland) for static cams. More problematic with mobiles - there are so many sites that have been used and it knows about that it can sound out a continuous stream of warnings (which can be verbal) which are worse than a nagging wife.It's basically like Google maps but with more driver orientated functionality.
