Verizon Wireless
The good: The Vehicle Diagnostics
system keeps track of your car's location and fuel level, and sends
alerts for maintenance issues. Users can access data on the Web or
through a smartphone app.
The bad: Without
an existing Verizon data plan, it costs $35 per month to run the
Vehicle Diagnostics system. It does not track fuel economy.
The bottom line: Delphi's
Vehicle Diagnostics system works best as a tool for parents who let
their kids drive the family car, as it shows the car location and will
trigger an alert if the car leaves a proscribed area.
