GPSmap60CS

My GPSmap60CS falls each time out. Sometimes, in a few hundred meters 2 or 3 times. No fun!
This afternoon the firmware once again put over the old one and let's hope he does not fail. But I do not think it will help. The system is yet almost 10 years old. Fingers crossed!
Next Sunday there is a walk about 10 km and then it is not amusing when the system goes down every hundred meter.
