While a passenger on a road trip today I played more with the etrex 30.
At one point it was tracking:
12 GPS - most showed a "D" (Differential from WAAS).
1 WAAS
9 GLONASS
With a claimed uncertainty of 3 metres. So far so good.
Then, I disabled WAAS, and with the GPS and GLONASS (more or less
tracking as above) it continued to claim 3 metres, which I found optimistic.

"I see!" said the blind man as he picked up his hammer and saw.
