I had mine updated by the dealer recently. I didn't have the confidence to do it myself.
In order for them to do it, they need an "excuse" from you before they do it (for free).
I told a little white lie and told them it was slow to boot up, and that once in a while the rear camera wouldn't kick in (actually happened once two years ago. Good enough for me).
Anyway, the service advisor knew what I was up to, and played along with me.
He just needed something to write on the work order before he could authorize it. It's a game.
Upgrade was done smoothly and easily by an experienced tech.
I subsequently did the nav map update myself. Piece of cake.
I'll do updates again before my three years are up.

Upgraded Firmware to the .352B. Took only ~25min, followed the attached pdf and everything went as they described. It retained all of my settings.

I do think booting is a bit faster (I had .100 FW before), too early to say if anything else changed.
