You can take precautions to keep thieves away from your GPS, but it wouldn’t hurt to prepare for the worst. GJ’s Computer Services Blog explains how to protect your information when programming your GPS:

• Do not enter your real address details in the My Home Location. People do this all the time, but this is the last piece of information you want thieves to have.
• Enter your street name or nearby street with no house number.
• Enter the address details of your nearest local police station.
• Create some other diversionary address that does not in any way lead to your property.
