I'm off on a road trip around Europe in mid-June. My car is a July '23 model, with no faults. Should I update the software in the car before I go, or after? I would usually go with the "if it ain't broke, don't fix it" approach, but to counter that, I always update my phone & Mac within a few days of a release/patch coming out. I know I'd get newer SatNav maps (pity those are not separate), but what else would I gain?
