It started with the62 series.
The 60csx had a better firmware (with accuracy circle)
it looks like, they changed the programmer team with the 62 series.
62, 64, 66 - all the same &§?*Ä (without accuracy circle)
Does anyone have infos if the programmers of gpsmap66 are still alive?

I also have big problems with calibrating the 66
calibrating a 60csx or 62 was very easy.
i already thought it might be a hardware issue ot the 66er series.
turning the unit quickly and not slow had more success.
or the will be an sw update in a few months or years
also with calibration , nord was not exactly north
