ShadowAuto is a plug-in OBD-II GPS tracker for anyone who wants to know where their car or truck is, without wiring, tools, or a technician. This listing includes a full year of ShadowGPS service in one upfront payment, so there is no monthly fee to think about for 12 months. Plug it into your vehicle's OBD-II port and it starts sending live location updates every 5 seconds while you are moving. Built for families watching over a teen driver or an aging parent's car, and for small businesses running a few work trucks, ShadowAuto pairs a permanent, vehicle-powered setup with real-time alerts for crashes, speeding, curfews, device removal, and geofence breaches, all through the ShadowGPS app on iOS and Android. It also reads your vehicle's OBD-II diagnostics, so you can catch a check-engine code or a low battery before it becomes a breakdown. Review a full year of trip history with animated route replay, and manage every vehicle on your account from one dashboard. ShadowAuto is backed by a US-based team with secure data handling and real support. After the first year, service continues on a no-contract plan you can cancel any time. | Shadowgps | | GPS Tracker for Vehicles – OBD-II Car Tracker Device with Real-Time Alerts, History & App – Vehicle GPS | Black | Best Buy
