| Hello,
Garmin has offered a new product: eTrex Vista HCx
Who knows something about the receifer, is it
much better than the receifer for the Vista C.
Thanks
Ernst

The "H" denotes the models using a newer high sensitivity GPS chip set.
That is a MediaTek chip set that has been described here as being as
good as or better than the SiRF III chip set.
The SiRF III set was used in the 60/76 Cx/CSx models but not in the
Vista models. So if all of this proves out, the performance of the "H"
models will be comparable to or better than the models with the SiRF III
chip set.
The "x" in the HCx denotes a model that uses a microSD card for external
memory expansion.

These are good news for me.
Do you know, if it is possible to store, calibrate and use
own maps on the eTrex Vista HCx?

yes - if the own maps are in Garmin-IMG format.
There are some tools to create such maps.

How does one transfer data to your micro SD card and not to your unit's
built-in memory? Say, I want to have one may on the unit and other
mapsource maps on the SD card.

The built in memory is not accessible for map storage on the "x" series
handhelds that use microSD cards.
When you create a map for a "x" series handheld from MapSource, it has
is sent to the microSD card. The microSD card can be in the GPS
receiver or in a card reader on the PC. It is faster to send a map to
the card in a reader than it is to send it to the card while it is in
the GPS receiver.
In some cases, like when you have unlock codes for more than one
receiver for the same mapping product, it is a good idea to have the GPS
receiver connected even when map is going to be transferred a card in
the reader and not in the GPS. That is to make sure that MapSource uses
the unlock code for the right receiver.
At any rate, with a card in a reader or in a connected GPS receiver, you
are offered a choice of the available destinations so you can pick the
one you want to send the map to. If you chose to send it to the GPS
receiver and there is no card in the receiver, it will halt the transfer
process. It will not send it to the built in memory in the GPS receiver.

Thanks Jack. I find this interesting especially since the micro SD card
doesn't come standard with the Vista HCx. Is the basemap any better
then the older units, say in the Vista or Etrex Legend units? In my
Etrex Legend, all I had was 8 mb + the built in basemap.

Tough question. As near as I can tell it is almost impossible to answer
the question coherently.
Various handheld models come with either the Americas Recreational or
Americas Highways base map. I'm only familiar with the one on my 76Cx,
which is the Americas Recreational.
To further the confusion, some the handhelds (my 76Cx for example) also
include the Marine Point Database (Americas). That is a most excellent
database of marine navaids and tide tables. But the fact that this data
base is included on some models appears to have been omitted from many
of the descriptions under the "In the Box" tabs. Looking a link for a
description of the marine Point Database, it says that it is included in
the following models:
eTrex Legend, eTrex Legend C, eTrex Legend Cx, eTrex Vista, eTrex Vista,
eTrex Vista Cx, eTrex Venture Cx, GPS 60, GPS 72, GPS 76, GPSMAP 76,
GPSMAP 76C, GPSMAP 76S, GPSMAP 76CS, GPS 152, Rino 120, Rino 130
So it would take some careful study of the base map descriptions (can be
gotten from a link on the "In the Box" tabs of the individual product
pages), then some calls to Garmin to sort out exactly what is on each
product, then you'd have to figure out what was on the older units, and
make a comparison.
The thought of figuring it all out makes my head hurt a little...
Garmin's merchandising concept continues to appear to be that you study
the issue until hopefully confused and then give up and buy one to see
what you get. :> )
