EDIT: forget the msg below. In part my problem stems from funky usb connector to the PN-60, it is hard for me to get a good connection. Even then, it only works in SD card reading mode, and then only on my Mac book pro. It looks like I am doomed to format one of my laptops as a windblows machine. How sad!!
END EDIT
I recently bought a PN-60 and have spend quite a few hours trying to make it work with ubuntu and first virtualbox and then vmware workstation.
My Zumo 550 is readily recognized by Ubuntu 10.04 LTS. But the PN-60 remains invisible.
If anyone has some bright ideas on what's funky with the PN-60 and Ubuntu, please give a shout.
Newer units like my Colorado 300 and Delorme PN-60 (unsure about Magellan units) have made things a lot easier for non-win users. When you plug them-in, they mount as a flash drive and you can drag and drop GPX files right onto the device.
Both the PN-60 and the Colorado also treat maps as files. Just drop a .img file into the /Garmin directory and it shows up. Similarly, Topo 9 comes with "pre-cut" map DVD's for the Delorme where you can also drag and drop the maps you want into the /maps folder on the machine.
However, to do firmware updates or to get imagery from Delorme Map Library or Garmin's Birds Eye will require you to use a VM or dual boot setup.
