NMEA sentences that look like this:

$GPZDA,213942,05,07,2006,00,00*41

You can select which ones you want to log.

- Is the SD DOS-Formated?

Yes, it's a FAT16 file system.  Tracks are logged to a file named
ccyymmdd_hhmmss.TXT in a top level directory named GPS_DATA.  A new track
file is started each time the unit is switched on.  You can optionally set
it to start a new file each time it reaches either 512k, 1034k or 2048k.

- Do you know if it can handle 4GB SD Cards?


Don't know.  The docs say up to 2Gb.  I've only tried it with 256Mb.

- Can i also use it like a normal USB-GPS-Mouse?


Not sure what you mean by this question.  You can download the 8k of
trackpoints (that can be stored in main memory) via USB.  I don't think
there is a way to access the contents of the SD card via the USB port.
There is, I think, a way of reading the track logs in real time from the USB
port, but I have not tried that (there is a setting called INTERFACE that
has the following options: NMEA, RTCM, BINARY if that means anything to
you).

- Does it have an external power supply for use in the Car?


Yes, that is a standard accessory, included in the price.

- Where did you buy it? At Storage Depot?


Yes, they seem quite reliable.


- The description says:
>   > Tracks 1 with max. 8192 waypoints
> Is that without a SD card installed?


Yes, the 8k trackpoints are stored in the unit's onboard memory.

- Do you know if the device has another name too, or the name of

The manufacturer is Taiwanese  http://www.scytex.com

  This might help me to find it at any german(or at least european)

Storage Depot is the only one I know of.

Thanks a lot
