[NTLUG:Discuss] Linux and GPS navigation

[Jack Snodgrass]

I am going to take a trip. I've got a Garmins GPS that I'd like to hook
up to my linux laptop. I'd like to be able to 

1) view a map on the latop and see 'where' I am...
and
2) view a map on the laptop and see where I've been.. and when 
I was there. 

does anyone know what software I should use? I've got the 
garmin map disk... but I don't want to run them on windows.... 
Can I use these 'maps' with a linux viewer or can I convert
them or what.... 

Any info would be appreciated.
