- I've been thinking lately (and I think I may have even mentioned it
- in another post) is that such a system could probably be home brewed
- which ought to reduce the cost quite a bit...
-
- The components you'd need are a GPS with a serial interface, a modem,
- an automatic voice/data switch, and a cellular phone.
-
- Let's see:
- GPS ??? (I think I saw this at Fry's Electronics for a couple hundred)
- modem $50
- Switch $75
- phone $400
-
- When you discover your car is stolen, you call your car with a modem
- and download the GPS data.
-
- Also, I wonder if one could hide a cellular phone antenna. If the cellular
- phone antenna could be hidden, one could use a wireless handset and take
- it with you much the same way you take along pullout/detachable-faceplate
- radios. This would reduce the chances of the theif breaking in since
- he can't steal your cellular phone. And even if he did, he wouldn't know
- to disable your anti-theft system
