As far as I know...
Top price - close to $10K for a marine quality unit with a large
screen, DVD player, etc.
Even if you just consider the range of prices for "normal consumer
GPS's", a range of under $100 to close to a grand doesn't fit my
definition of "they all have comparable prices".
Sure, maybe if you base the price on a feature for feature comparison,
they might have comparable prices, but that blanket statement doesn't
work for the entire range of devices available.
Man, you WERE stupid! Units all over the place for half that. What
motivated you to buy a $700 unit? Mine was a gift at $100, and their
smallest unit. I'd buy another in a second if this one dies, and I'll just
skip it like a stone at the lake and not feel bad.
Acquisition times for the Garmin Nuvi line can vary from instantaneous
to "Heck, I could have been there already!" I can't speak for other
It all depends on how long the unit has been off or how far you've
moved since the last power down.
If the unit has been off for more than 4 hours, it assumes the stored
satellite data is stale and starts from scratch. The same thing can
happen if you move more than a few miles from where you powered the
unit down, although that is not as clear cut. These acquisitions time
can be upwards of 2 minutes.
The longest acquisition times usually occur when both of the above
conditions are true *and* you are moving at the same time. These times
can be excruciatingly long.
If I have absolutely no clue where I'm going and know that the unit
will take a while to acquire the satellites, I'll pull over or not
leave the parking lot until the unit is ready. There's no sense in
driving around while extending the acquisition time, only to find I've
been going in the wrong direction.
Exactly, the data rate for the almanac is quite slow and moving only
TomTom has a nice feature where you can preload about a weeks worth of
almanac data available via their management software.
