I've no experience of the Honda system, but I do have a Vauxhall which came with 2012 mapping, which I did update in 2019. To be honest, the old maps very rarely caused me any problems, apart from a few roundabouts missing and altered junctions, and of course any new build developments were completely missing.
What I do find useful over a stand alone satnav is the fact that radio audio is muted down when the satnav is giving instructions. I like music on a long journey, and I occasionally didn't quite hear the odd instruction fully, so had to look at the screen.
Although it's an older system, they still produce annual updates.
