Shake sensor shock sensor for GPS106A/B/C,TK106A/B/C,GPS107A/B/C,TK107A/B/C,GPS103A+,GPS103B+hiqh quality 100%

Amazing item, works flawlessly. Installed it in my BMW X5 e53 just below the CD changer/navigation unit in the trunk. Set the sensitivity like 30 degrees below MAX and it detects any moderately strong shock from any side of the car and so far did not falsely go off from loud car engine roar in parkings or the like. See attached pic. BTW, the Sony head unit is where I have hidden the SourcingBay TK103B+ tracker so I am using it as a box to hide the tracker.
