You can follow the step-by-step download instruction on the left of the web page to install ZGPS from your PC to PDA:

Click on "Live" you will see "Weather," "Google POI" and other live functions, such as "Hotel Deal" and "RT Traffic." I am using a purchased copy with all options selected for more than a year now, but I don't remember whether the trial copy activates these paid functions or not.
