CABRAMATTA police are urging car owners to take precautions when leaving their vehicles unattended.
Police arrested a 28-year-old Cabramatta woman and a 40-year-old St John's Park man on December 1 after they were found in possession of a GPS Navman, which police allege had just been stolen from a car parked in a unit complex on McBurney Road, Cabramatta.
The woman was charged with stealing and goods in custody, and was granted conditional bail.
The man was charged with stealing, possessing implements and having goods in custody.
He was refused bail and will appear in Liverpool Local Court next Monday.
Cabramatta local area command's acting crime co-ordinator Sergeant Brett Grenfell said there had been a spike in stealing from cars over the past two months.
"In October, there were 25 incidences but in November that figure spiked by 12," he said.
Cabramatta police station's crime prevention officer Constable Stevo Jokic said taking simple preventative measures reduced the chances of becoming a victim.
"When you park and leave your car, it's a good idea to do a quick checklist," he said.
"Ensure the surrounding area is well-lit at night, personal valuables are stored out of sight or taken from the vehicle, and doors and windows are locked — it's as simple as that."
He said it was crucial for car owners to take valuable items out of their vehicles, especially when they leave their cars parked in driveways, open car ports and on the road overnight.
"Thieves usually steal items like MP3 players, mobile phones, cash, laptops, GPS, CDs and CD players," Constable Jokic said.
"People should take these items with them when possible, or at the very least, store them out of sight in the vehicle.
"Thieves usually gain entry by smashing a window so it's also a good idea to park in well-lit, busy streets whenever possible."
