Someone on priusonline.com claims that his works perfectly well mounted
down under the radio, in front of the cupholders.

Unfortunately for me, that's where my XM radio is....

I don't have a Prius yet but I do have a Garmin C340 and I love it.  I
ordered an inexpensive tiny antenna with a long cable on it and can
mount it anywhere in my car.  I can also use my PC, no idea about OSX,
to program it and put custom points of interest or way points in.  For
example, I have all of the radio stations by categories such as talk,
jazz, news, etc.  I can just touch that item on the screen and it
gives distances and directions as well as frequencies.  If I want to
listen to NPR on a trip I can use my GPS to stay tuned to those
stations.  I love the flexibility of the Garmin.  See http://www.poi-factory.com/
for tons of custom way points that you can download and install on
your unit.  I have experienced the built in GPS and would vote for the
portable one. In my PT Cruiser it is not that obtrusive mounted on the
windshield but the Prius has a slightly different configuration.  With
the antenna extension you can put it anywhere.

Other Garmin models may be different, but our C330 has a connection for a
remote antenna. We put the antenna on the dash near the right corner - it is
small enough to sit there on its own - and put the unit between the front
seats. There is a configuration item that has to be changed for the external
antenna and changed back when it is not being used. In a more permanent
installation the antenna could be put under the dash if desired.

The built-in system in the Prius offers a few advantages over a
portable GPS unit.

* uses existing (often larger) display screen, touch and voice
activated
* uses existing audio (mutes radio for directions on driver's speaker)
* has dead-reckoning ability.  The Prius' navigation uses a series of
gyroscopes and the vehicle's speed sensor to know how fast it's going
and of any turns made, and can plot this on the map, even if the
navigation system has lost all satelite contact (such as in a long
tunnel or parking garage complex).
* uses car's own charging system (no batteries to change out or messy
charging cords)
* difficult to steal or accidentially misplace/lose
* single DVD, so no swapping out of discs or memory cards when on a
long trip.  (US/Canada on one DVD, for example)

However, a portable GPS system has a few advantages over the built-in
system in the Prius:
* available often for cheaper than the built-in system
* can be added after purchase
* can be used in other vehicles, or when walking/biking/etc.
* map/POI updates are often easier to get, more frequent updates, and
may be cheaper (if you only update your local area and not the entire
continent as on the Toyota system)
* may have some features (such as breadcrumbs/remembered routes) not
available on the built-in system

Toyota doesn't have update DVDs very often, but they're usually in the
US$50-$00 range...  If you are in Europe/UK, you can lookup DVD
updates and purchase through http://www.toyota-mapupdates.eu/default1.asp

Do note that you cannot easily add the factory Navigation system to a
Prius not already built with it.  (At least 2X the parts cost alone as
compared with the option pricing, let alone a lot of labor...)  So if
you want it, you'll have to order it that way.  US 2007 Prius option
packages #5 NL, #6 NW, Touring #5 NM, #6 NR, all have the factory
navigation included.  If your local dealer/region doesn't offer the #5
NL or NM, you may want to see if your dealer is willing to swap
outside of your region, or else you may want to yourself go out of
your local region to get the package you want.  Try different ZIP
codes in the "build and price your Prius" link on the left side under
"Shopping Tools":
http://www.toyota.com/prius/options.html

Yes, the Toyota system has a speed lockout of most Navigation buttons
when you are moving.  (Home and the 4 or 5 preset destinations still
work, as do various voice commands.)  For 2006, a larger display (with
better resolution) and newer navigation system was added, which
doesn't accept the known screen button hack to allow use of the screen
while in motion, but now does allow destination input by voice
command.  (Voice commands are usually spotty at best.  8(  )

If you really are annoyed by the speed lockout, you could purchase a
Lockpick:

As to whether a portable unit or the integrated Toyota unit is best,
that is really a personal decision...

together
some random words that came up with:


What I did what get a Garmin 7500, get the external plug-in antenna and =
have
someone mount it under the dash in the center by the front window, and =
hang the
nav in front of the plastic tray with the smokey fold-down plastic piece =
in the
center of the dash by the front cup holder.  Any good car stereo shop =
will fix
you up with plug in power and mounting.

Then you have a FAR BETTER nav then the Denso nav that Toyota uses, you =
can take
it out when you want, and you can update the database over the web with =
SD
cards.

A bonus to this is that the nav screen doesn't get washed out by the sun,=
 and
you can keep the consumption screen on the regular display together with =
the nav
screen.  Also, you don't have to put up with the the lockout.
