What I mean by that is if you set it up to show the milage screen then stash it you can open it up later and see the milage. But if you unplug it it will show something else and you would need the. Buttons to change it back.
Really it's a personal thing doesn't impact anything lol just my anal retentiveness coming out
To be honest I haven't looked at mine in ages. I checked it out like a week after and it was doing good. Now I kinda wanna go look see if it's ok lol
