Installed Sygic Drive, another PDA gps navigator that also works in Windows. It’s running thru wine in Ubuntu. Map files where a bit tricky, requiring a properly configured *.mlm file and an activation code for the maps.
Installed Igo 8 in my Ubuntu Netbook Remix, was pretty easy just install wine and you’re good to go. I needed to create a symbolic link from the bluetooth /dev/rfcomm0 to com1 in wine. Just went to ~/.wine/dosdevices and did a ln -s /dev/rfcomm0 com1.
