Rynn01, please note that Plucker is an
offline reader and Sunrise is a program that downloads content for Plucker when you hotsync. That means that you have to download content ahead of time and save it on your PDA, can't surf the web in real time. So Amazon, Google, etc. would be of little use unless you had a page for a specific product that you wanted to view. If you have wi-fi or bluetooth access to the internet in your PDA, you could use a web browser (like Blazer) to surf in real time.
As far as viewing maps goes, Plucker conceivably could display a simple page from mapquest, but it's really not well suited to viewing large graphics or pages with interactive content. Try this-- go to this website in your browser:
http://wap.mapquest.com and get it to display the map you want, then right-click and clip it to SunriseXP, and view in Plucker.
Hope this helps!
