Since I installed the update prior to last weeks release I've noticed that on my unit things have changed with my built in c-map and c-map reveal card. Now my c-map reveal card is called c-map onboard and built in is c-map NA-Y214. I dont remember them being like that. Also since the update on the built in map I got alot of brown/tan areas that are showing up in the middle of the lake. What could cause that?
Thanks
