depth data on etrex 20x

Hello i am new to the forum,
I just purchased etrex 20x and copied VEU015R map on it. Everything seems to work normal exept i can't see depth measurment on the unit. Using homeport softwate i can see depth measurments on the map normaly. Thanks in advance for any help.

PS: sorry for bad english

edit: Found the problem. In marine map setting i had to activate the "soundings" setting to on.
