Now,i cant afford a tracker system to be installed but got thinking about if i hooked up a small mobile phone to the 12v system of the car (via a car charger for the phone etc) and then if the car got nicked i could at least try one of those trace a mobile sites

Now,any ideas to perfect this idea ? (and no smart **** buy a proper tracker) as they are just as crap as my idea for being overcome (NCP car parks etc)

so,thoughts ??

cheers
