I have recently got a 35 Touch, and it just will not connect to any Glonass satellites when GPS+ GLONASS is selected. All the Glonass Satellite numbers just flash and don't lock and only the GPS ones lock. i have synced with Express on my laptop, full factory reset, deleted the CPE and position files and re synced with express and still the same it is only locking onto GPS when they are both selected? Is anyone elses like this? Also the tracking is quite poor on it and only goes down to around 15ft accuracy.

Any suggestions ?

Due to not-so-recent-but-still-current world events, I'm not sure anyone is enjoying favorable results from the GLONASS positioning system.

Glonass works fine on my 65s and Etrex 20x..

It seems to work ok on the Montana 700 and GPSMAP 276CX, but the Montana 610's we use keep losing reception unless it's disabled, been this way for a while now.

OK, we dug an eTrex Touch 35t out of mothballs, installed some fresh alkaline batteries, and let it rest on a window sill for a few hours. It never did find/use any GLONASS satellite signals. Best accuracy achieved with GPS + GLONASS was 13ft, while GPS Only provided 9ft.

Here in Europe I am receiving data from four GLONASS satellites on my Oregon 700, no difference in accuracy.
