Thread: Garmin Aera 500 in Aera 550

That certainly eliminates region 140 as enabling features then. Back to 16 as the likely source of feature suppression in 500. Because all the aera 5x0 hardware is identical and they use the same firmware the features are already present in the firmware. There are references to 'J C V' and 's a f e t a x i' in the firmware for example. We need someone to supply a copy of rgn16 from a 550 or 560 or someone who's done the conversion in some other way to post with info about it.

I'm trying to find someone with 550 model too.
