If we don't put the multi bands, we are exactly like the 66s it seems to me, but it is certainly not the same GNSS chip.
But the 66s does multi-GNSS, doesn't it? And the 66sr turns off mult-GNSS if you turn off multi-band. At least mine seems to.
So a 66sr with multi-band turned off is worse than a 66s, because the 66s will also pick up other GNSS systems, and the 66sr only the US GPS.
Sorry, I was wrong. My 66sr (firmware v5.50) can in fact do multi-GNSS with multi-band on or off, as well as GPS-only with multi-band off.
What it can't do is GPS- only with multi-band on. It just refuses. If multi-band is on and I change Satellite System from Multi-GNSS to GPS-Only, then Multi-band gets switched off.
This corresponds to the 2nd screen shot on "Pages > Satellite > Satellite Page Display" (GPS Only, Track Up, Multicolor, Multi-Band On). I cannot get mine into that mode. Can someone confirm that their 66sr can do that, and if so what firmware version?
I downgraded my GPSMAP 66sr to firmware v5.20 and this limitation also exists in that version. So it is not a new problem in v5.50.
Except that now with v5.20 I have no problem finding satellites with multi-band/mult-GNSS, so I can't see any reason to even try GPS-only with multi-band.
