Why do I have to pay an annual fee to keep my navigation up to date?

I've recently noticed that the sat nav on my 3 year old BMW 3 Series is out of date and no longer providing real-time traffic updates. My local BMW dealer suggested I need to purchase an annual subscription...

Who is reponsible for updating sat nav information?

A local road had its speed limit reduced from 40 to 30 in August 2023 but the GPS in my car still shows 40. Who's job is it to get a database updated when a speed limit is changed?

Who provides traffic announcements?

I drive a 2018 Suzuki Vitara which I bought in 2021 and still remember the first time I heard a loud announcement in the car telling me 'Caution, A406 traffic disruption, speed 30km' It was quite a surprise...

Why has my VW satnav stopped giving traffic updates?

My satnav no longer picks up traffic, roadworks etc. VW tells me it is no longer supporting its own satnav. Is that genuinely true?
