192 Northstar 8000i Operation Manual
There two types of upgrade for a 8000i processor.
1. Software patch upgrade. This is a quick procedure using a small file
that can be downloaded from the Northstar website
www.northstarnav.com or from a Northstar dealer. This method will be
used to fix known issues or for minor feature additions. Install this on to
the system master. Other processors will upgrade off the master unit
2. System image upgrade. This is large file that can be downloaded and
will be available from Northstar dealers on DVD format. This will erase
the current system software and replace with a new version. It will not
remove user settings such as waypoints, routes and page settings. This
system will be used when major features have been introduced that
require changes to the underlying operating system.
A power disconnect during upgrade or installation will corrupt the system completely.
To avoid loss of information such as waypoints etc. always back up your information.
When upgrading a multi-processor system. Start with the system master. When the master
is being upgraded, all other units will be unusable and display a message alerting the user
that the master is being upgraded.
