Now that's a polite reply with some thought behind it. Capital and bold letting just means I'm being shouted at or treated as an idiot. I'm sure 99.9% of folk on here do realise that GPS/Infotainment systems can have some misgivings.It's not a case of that. More pointing out that no matter what a Sat Nav is never going to be up to date. Until real time updating is in place.
Not sure if that is possible at the moment, as to many mapping companies & no real way to keep it updated.
I guess if all cars had the camera that picked up speed limits, and the facility to upload that data. GPS tracking for new roads. It could be possible. But who is going to provide the mapping? Fund the cost of data?
IMHO any assistance is good and I believe a warning is better than an action so an audible bleep might be effective each time the speed limit display changes. We can all live in hope.
