I like the idea of an app that helps me find my car in a huge parking lot or garage. But VisionQuest Carfinder costs $20, which strikes me as a bit high for a BlackBerry app that promises to find my car automatically (that is, I don't have to set the location of the vehicle in my phone--I just walk away). How does it do it? The app requires pairing your BlackBerry with an in-car Bluetooth device--any Bluetooth device will do--which it then communicates with to locate your car. If you don’t have a Bluetooth device in the car, you can use a manual mode that lets you set the car's location via GPS coordinates in your BlackBerry. But I can mark my car's position with all manner of GPS apps--less-expensive ones that do a lot of other cool GPS functions, too.
