Hello. I have a 2008 Toyota Prius 2nd generation. It has 250-ish thousand miles on the car, and I was looking into updating my DVD map, and I was looking on eBay, and I found a 14.1 update DVD Navigation North American DVD, and I was unsure what the update means, like does it mean it has updated roads from 2024 or 2016? Also, if anyone has updated their DVD maps, what are some things you need to look for to make sure that the DVD will work properly? Thanks.
