Help with Garmin Software

Hi everyone,

My first post. I am a new mac owner and have a Garmin 60Csx GPS as well as City Navigator and Topo Canada software which is for my old PC.
I have loaded the following in my mac:
Garmin MapInstaller
Garmin Mapmanager
Garmin Road Trip

I have then been following these instructions to get the maps converted from PC to Mac.
http://www8.garmin.com/manuals/MapSource_MigratingGarminMapProductsfromWindowstoMacComputers.pdf

So I have the first file for citynav on my mac harddrive but when I try and open it it will not archive. It comes up with Error 2 - no such file or directory.

Not sure why....the file is the converted file from Mapconverter and is a TGZ file.

Any ideas or better ways to convert my software?

Thanks

Make sure the Garmin software is made for Mac OSX:
Garmin | Mac OS X - Current Software, news and more

Yep, installed the MAC OS from that site.
