Yesterday my navi was unable to correctly track my car. It was off by maybe
half a mile. After awhile it seemed to be ok.

Yesterday there was heavy cloud cover and storms. But I didn't think this
could affect GPS reception. Any ideas? (There was nothing covering the
antenna area in the rear.)

 

My 2000 tends to have reception problems when there is heavy overcast.
There is a weird icon in the upper corner of the screen. It changes color
to indicate the status of reception (red - none, amber - flaky, green -
good).

I have a hand-held GPS and it is much slower to acquire satelites when
it is wet and heavily overcast. I was in a hertz car with their
never-lost gps in fog and the unit couldn't pick up satelites at all.
(Interestingly, though my handheld worked.)

The accuracy of the GPS is related to how many satelites it is
reading. I was in boat the other day with clear weather and the unit
showed like 9 satelites. It seems to be able to get an initial fix
with 3 but sometimes the accuracy is low.

So, I wonder if maybe the unit was simply unable to acquire enough
satelites to get an accurate read.
