Thread: GPSmap 66st resets itself after conecting with pc

First, sorry for the bad English.

I have just bought the Gpsmap 66st, and have some problems with it, when I use Baseamp.

Some times when I'm connect to BaseCamp, i get a message-box. (see picture).

Spoiler: screenshot

Quick translation:

The following elements can not be transferd

1 Waypoint
2 Routs
3 Tracks

Unit does not support the GPS-elements or BaseCamp need upgrade.

Press OK to transfer the other elements you have chosen (if there are any)


It has happen many times, and usually it works, but three times, the result is that the 66st, is get restored to factory settings.

I have the latest v. og BC, and even re-installed it.

Any idea?
