GPS - editing-renaming waypoints problem - goes back to map

[Bing]

I bought a new eagle fishfinder/gps last year and when I try to rename or edit a waypoint the unit keeps going back to the map screen before I can finish editing the waypoint name. Do I have to have the memory card in the unit to do this? Or is there something I am doing wrong obviously? Thanks again for your help. Bing

I find the easiest way to edit/rename is to download them to your computer and edit with the software most gps come with, then upload them back onto you gps

also if anything happens to your gps you have a backup of all your waypoints

I have a Lowrance and every now and then I forget to press "enter" after every change I've made. If you make the change and press"exit" to get back to the previous page, the change will not take effect. Is it possible this is happening? Andy
