Firstly you need to select a site to inspect. The PDA provides a complete list of all sites alphabetically, the route order lists (as defined within the configuration of the office system for all routes just in case you get asked to cover), a list of inspections that have been scheduled and also a list of any inspections that have been suspended and are awaiting completion.

Again the PDA will highlight the last site you were at for information with simple point and tap menus and scroll bars for navigation.
