!!! GPS Support

[{TableOfContents}]


\\I have a Garmin GPSMap 60 CSX that I use for both Geocaching and as a Car navigation system.
\\Unfortunately, Garmin is reluctant to supply proper software for the linux platform, and now Garmin MapSource is the only reason for me to keep a Windows environment at hand.

I also needed a more convenient way to transfer waypoints to my Garmin device with Linux. Here a log of actions done in order to achieve that :

!! Install software

! GPSBabel

This comes standard in the Ubuntu distribution and can be installed the usual way.

! Garmin USB driver

Some more info on [http://www.gpsbabel.org/os/Linux_Hotplug.html]

To allow the USB devices to be read and written by a non-privileged user, create a file called  ''/etc/udev/rules.d/51-garmin.rules'' with the following contents: 
{{{SYSFS{idVendor}=="091e", SYSFS{idProduct}=="0003", MODE="666"}}}

This driver (''garmin_gps'') is also included in the kernel, but in order for GPSBabel to work properly, it must be uninstalled: {{{ sudo rmmod garmin_gps }}}
\\To make sure it doesn't get loaded after the next reboot, add the following to /etc/modprobe.d/blacklist:
{{{# this driver is in the way for GPSBabel
blacklist garmin_gps}}}
\\After plugging in my USB-connector, the following is displayed by lsusb:
{{{
root@bismarck:~/gc# lsusb
Bus 005 Device 003: ID 05e1:0501 Syntek Semiconductor Co., Ltd 
Bus 005 Device 001: ID 0000:0000  
Bus 003 Device 001: ID 0000:0000  
Bus 001 Device 001: ID 0000:0000  
Bus 002 Device 004: ID 091e:0003 Garmin International GPSmap (various models)
Bus 002 Device 003: ID 046d:c03e Logitech, Inc. Premium Optical Wheel Mouse
Bus 002 Device 001: ID 0000:0000  
Bus 004 Device 001: ID 0000:0000  
}}}

Now I can transfer waypoints, for example : {{{gpsbabel -i garmin -f usb: -o geo -F test.loc}}} copies all the waypoints from the Garmin device to the file test.loc. Nice !
\\However, only when you're root, if you're not root, you get :
{{{
metskem@bismarck:~/gc$ gpsbabel -i garmin -f usb: -o geo -F waypoints.loc
usb_set_configuration failed, probably because kernel driver ''
 is blocking our access to the USB device.
For more information see http://www.gpsbabel.org/os/Linux_Hotplug.html
}}}

So I first rebooted, to make sure that the garmin_gps driver is not loaded, and that the permissions for the usb device files are correct. After that I can also transfer waypoints to/from my Garmin device without the need to use root privileges.

!!A few examples:
* Send (just downloaded .loc file to usb device  __gpsbabel -i geo -o garmin gcjpq0.loc usb:__
* Download (backup) all WP's from usb device to local file  __gpsbabel -i garmin -o geo usb: allwaypoints.loc__
* Download (backup) all WP's, tracks and routes from usb device to local file (with some debugging) __gpsbabel -r -t -D1 -i garmin -o geo usb: allstuff.loc__
