There have been multiple reports by users of the GPSMAP 64 series (non 'x') and the eTrex Touch 25/35 series indicating complete failure to obtain GLONASS satellite signals. These devices all use the same MediaTek MT3332N GNSS chipset.

The Oregon 6x0, 7x0 and Rino 75x also use this GNSS chipset.

Anyone having any GLONASS reception issues with those yet?

My Oregon 600 can't find GLONASS satellites.

Just like another user here.

It looks like Oregon 600/650 are now GPS-only devices.
