Download Navgps Pro (version 4.5) release notes

The PocketPC version is installable on secondary storage (e.g. compact-flash memory). During installation, the install software will prompt whether you want to install in the default folder. At the prompt, select 'No' and then select the secondary storage folder.

Depending on where you are, you might have to download topography maps also.
