10. Vehicle Locator

Device Name: PocketFinder GPS Vehicle Locator
Price: $189.95
Complex Says: The PocketFinder GPS Vehicle Locator helps you use your iPhone, iPad, or iPod Touch to locate your vehicle. While the company touts it as a tool for parents to be able to supervise their children while driving, we think it's more useful to find a map location of your car if it gets stolen while you're away from it. There's a service fee (the purchase of the device includes two months' worth), but the peace of mind can be worth the purchase for someone who travels a lot.
