 Garmin's StreetPilot onDemand iPhone app was designed with city dwellers in mind. Along with the usual auto-routing and turn-by-turn features, the new GPS app offers public transportation routes. People in big cities who rely on public transit can access their bus and train schedules through this Garmin app. The StreetPilot onDemand is available now in the App Store. For a 30-day trial, users in the United States and Canada only pay $.99 to test out the features like voice-prompted navigation. Once the 30-day period is over, users have the option of a monthly for $2.99 or yearly subscription for $29.99. Starting today August 31 and running through September 14, Garmin is offering a special introductory price of $19.99 (a $10 savings) on yearly subscriptions of the StreetPilot onDemand app. |
