tracker
the original tracker is good and has a very high recovery rate,gps trackers are good but not so when parked in garages as satellites cannot see.
i have been fitting trackers to cars for around three yrs now some cars being worth £120,000 and its more than my jobs worth to do a shite install ,tracker themselves expect high installation standards and qc random cars .any installer doin shite installs has all the other cars he has worked on checked by tracker if caught
