Potential GLONASS Reception Failure

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?

Oregon 700, firmware 6.00
GPS + GLONASS + WAAS/EGNOS -
works flawlessly

It does work fine on my Oregon 700 too. I'm using only GPS though, GLONASS has no added value for me.

In good conditions yes. But when conditions worsens (eg. tall buildings), adding GLONASS increases accuracy and stability (less drifting) for me.
Fortunately Oregon 700 works as expected, but I am frustrated that GLONASS is suddenly gone for other devices (eg. Montana 610/680).
