I’m not sure how much of a demand there will be for an app that lets people know where your at on Facebook of all places, but it may be useful for hardcore Facebook fans who don’t have too many options when it comes to sharing their location with friends and family, especially with Facebook not offering a native application of its own. So VZ Navigator’s Facebook location integration could be useful for a certain type of mobile user tied to Verizon Wireless.

It’s also not free. It will cost $9.99 per month for $2.99 for 24hrs worth of usage. But, the price also gets you other features like turn-by-turn navigation and a roadside assistance feature that sends your location with a click of a button.

Some of the other features:

Other new features now available with VZ Navigator 5.0 include:

• Improved Customer Experience – No need to wait for the entire route to download before starting their voyage because data will now be streamed, causing display screens to populate more quickly
• Enhanced Points of Interest – Access to premium places of interest with detailed descriptions, clearly branded by Map Icons
• Traffic Crowd Sourcing – Opt-in to anonymously send real-time location and speed to the VZ Navigator traffic reporting service, allowing quicker notifications and improved accuracy for all VZ Navigator users
• Alerts for Other Road Attributes – Graphic notifications for tunnels, U-turns, traffic circles and toll plazas
• “Say it Mode” – Select BlackBerry smartphones and Windows Mobile handsets allow customers to verbally search for and update destinations

So $9.99 may just be worth the price.
