I did not buy an update, but I had a bad SD card replaced in Aug 2022. Took the dealer all of 5 minutes, meaning there was nothing needed other than replace the SD card. Of course, it took them months to finally arrive at the conclusion it was a bad SD Card, after me suggesting that 2 or 3 months earlier. They insisted in trying a software update that GM was working on, even though the TSB said for hard failures like mine, they should replace the SD Card. I tried showing them their mistake but despite all my efforts, they would not listen to me. End result, they tried the first thing last and got a severe rebuke from the service manager, who refunded me the money I spent on car data for a trip to the US. As he said to them, they need to LISTEN to what the customer says, as they kept writing my problem up as intermittent, even though 5 or 6 times I pleaded with them to change it to a hard error.
I digress, relived bad memories there. The other point is, the 22 has Android Auto, which IMO is a way better and more accurate Nav tool. The only reason I have built in Nav is because I bought the car during the pandemic, it was the first one available and I needed a car yesterday. I had reserved a different Nox without nav but my 13 Nox decided it would not last until that came in.
So.... yes, it is that easy to swap the SD Card and nothing bad can happen, unless it is a bad SD Card, at which point you can put the old one back in until the new one is replaced. But why spend the money when Android Auto (or Carplay) is available on your car for no cost except for phone data? We even (finally!) have decently large data plans in Canada at an affordable price that also give US coverage. AA has real time traffic updates that the built in Nav does not have, unless you subscribe to Onstar (no thx), I imagine Apple CP is the same.
Unless for some reason you REALLY prefer the built in NAV, I think there are better ways to spend the money, but to each their own.
