My truck was stolen yesterday in Houston

They'll look for easy things like a starter interlock and you can bypass one with a screwdriver.

Things that will make her more difficult to steal.
Hidden brake line locks on the disc brakes.
Hidden PCM power lockout.
Hidden fuel pump power lockout.

Lojack is the technology of the 1980's based on a radio transmitter and proprietary hardware in the police cars.

We have access to GPS and mobile phone networks now.
I hack embedded interfaces for work...
I have existing AVL applications for the LMU4200 series and since they are the size and weight of a pack of cigarettes. You could bury them above the headliner with industrial Velcro or in the dash or in the cab corners behind the speakers or... Anyone can buy a refurbished GPRS LMU4200 for around $30 and a glass mount GPS/GSM antenna for around $30 but you'll need to roll your own AVL app for the LMU.

There are tutorials for rolling your own very small GPRS vehicle locator by building on a small embedded development board like the Intel Galileo, TI 430, Arduino or Rasberry Pi.

The only way to access either my system or the DIY units is to know its' phone number or intercept the traffic to the location server or text messages to the unit.

Face it. None of us are interesting enough that anyone would be interested in going to the lengths necessary to hack a home brew embedded AVL CPU to find out where we are.
