@catmag I dont have this Problem when i delete all Favouritis they are gone... as they should... Maybe because i use a additional mini SimCard...

-As i read in a forum other people can Delete or modifiy Data on other Gamrin Device . I can modify the Data on the addtional mini SimCard(external Memory) when i connect my Garmin device to Basecamp.. But not on the internal Memory.

So i could use only the external Sim Card. But the Problem is when I create a new waypoint its on the internal Memory. So i have to copy it from internal to external Memory with Basecamp and then delete it manualy on the internal ... Quite a lot of work !!! So i Call it a Bug in BAseCamp !!!! Because BAsecamp not Support NÜVi 13xx. So i guess i have to find a Garmin Device that work properly with BAseCamp.. Or find a Dokument thats say which Devices works correctly with bascamp !!!

MAybe i should ask Garmin Support ....
