I pay $4.99 per month for Verizon Wireless's VZNavigator. VZNavigator is a Brew based LBS applications that gives turn by turn directions, local directories, maps. VZNavigator has gotten me out of many a hairy situation. The past few times I have used the application, however, I get a sporadic error telling me it is unnable to retrieve the directions I have requested.
When this happened to me today, I decided to try Google's SMS directions. I sent "directions from (my work address) to (graphing social paterns conference address)" to the short code 46645 (GOOGL). Within 30 seconds I received three messages including the turn by turn directions. So while I didn't have a friendly voice dictating to me where to turn, nor access to a map, I was able to get to my destination just fine. I must admit it is pretty tempting to want to save myself $5/month going forward... Especially when it takes almost the same amount of time and effort to type the directions request onto the SMS message, than to navigate through the device's convoluted menus to get to VZNavigator.
