I know this peaty well. I'm think i'm not a noob in Garmin. But i'm updating my device trough LifeTime Updater and i'm sure that Garmin checking the verssion of the installed map. This is the reason that i don't want to mix the maps. And there is a certificate file. But i still don't understand, how CX can work with the unlocked map and don't work with a certificate map?
Thanks.
