Access Google Maps on your webOS device [webOS 3.x] 6
This tip is only for devices running webOS 3.0 and higher
Although Bing Maps has replaced Google Maps as the standard mapping app in webOS, you can still access the http://maps.google.com website to satisfy any Google Maps needs you may have. Upon launching the site for the first time, you will get a prompt to allow the site access to the location services on your device (you can decide to allow it just once or always allow it, or decline altogether). While the Wi-Fi TouchPad does not have GPS, it can approximate your location pretty well using Google Location Services that uses the Wi-Fi networks in range of your device.
The version of Google Maps that will load up is the mobile version of the site, not the full desktop version. While there are a lot of features available to you, from driving/transit/walking/biking direction, layers, tap-to-identify location and more, it's not a perfect solution. There are many things that make using the site difficult to use, including the lack of pinch-to-zoom and the inability to pan around the map, but it's still a resource available to you if necessary. You can also access the full Desktop if you want by tapping the icon to load up the driving directions screen and then choosing the "Classic" option. You will still be limited with how you can interact with the map (zoom, pan, etc) and it won't find your location automatically, but there are some additional features available to you.
