Gps For Zaurus, list of compatible models Options

[drakecoldwinter]

Is there somewhere a list of compatible CF GPS cards for Zaurus ? I am looking over ebay and sometimes some GPS cards go out for only 30$ but I don't grab them out of fear of not working under Zaurus (I use cacko 1.23 on a 3100) I know that the software support is very weak and poor, but even them I'm interested in the GPS card as I know is only a matter of time before someone adapts Tom Tom Go or something like that.

So my question is, can I grab any GPS CF card and use it or I need to check for special drivers for the zaurus in wich case where can I find a compatible list?

thank to all.

There aren't any real model variations as far as the Z is concerned; you really only need to choose based on chipset(go MTK or SiRFStarIII) and price. Any USB GPS 'mouse' will present itself as a USB serial device to the kernel*, and will spit out NMEA data when opened. And everything understands NMEA.

Installing gpsd is a good bet; many linux gps utilities use it, although most can be configured to read the GPS serial device directly.

(* there's a chance that the USB serial chipset might be unrecognised by linux, but I think support is getting very good these days...)

The bluetooth GPS units are essentially identical; but use a BT serial link instead of a USB one.

I don't think there's really any standard for serial over usb, so you need a driver for whatever is in your device. For example, to use an itrek-z1 over usb under linux you need the cp2101 driver in the kernel.

What I want is:

-USB (not bluethooth)
-Works well with pdaXrom
-The ability to upload data to Google Earth or a similar app ( not compiled yet is OK)
-Externally powered would be nice, or not too draining on the battery

You should check out the itrek-z1, it outputs NMEA over usb and bluetooth, is self-powered (with solar panel for extra life), can records tracks itself, and there's java software to config the device and download tracks over usb and convert into a kml google earth file.
