L.A.S. 3100 Series FAQ:

Does the unit come with everything I need, including software?  
Yes.  The price includes the GPS tracking unit, Software with mapping and satellite imagery for the entire U.S. and the download cable to connect the GPS unit to your PC.

What is the difference between the 3100-INT and the 3100-EXT and where can I mount it?
The 3100-EXT model has an external (EXT) GPS antenna.   If you have to place the unit underneath the vehicle and do not have enough room inside bumper you may need the EXT version.  For inside the car placement most people get the INT.  You can place the INT model in the glove box, in the bumper, under the front or rear dash, and even under the seat.  Under the seat placement is not really recommended but we have received numerous reports on how well the unit works even hidden under the seat.

If the batteries go dead before I am able to retrieve the unit, will the tracking data be lost?
Of course not.  The unit uses flash memory which does not need a battery backup.

Are the 3100-INT or 3100-EXT units  water-resistant?
The units are very water-resistant.  However we do not guarantee the units to be 100% water-resistant.  When placing the unit on your vehicle, make sure it is not subject to splashing water.  Our warranty does not cover water damaged units.

How many days can I expect the 3100 unit to last without the batteries going dead?
With regular alkaline AA batteries you can expect about 36 driving hours.  Therefore, if the car drives about an hour a day, the batteries will last for over one month.  If you use Energizer Lithium batteries, the batteries will last close to 80 driving hours (2 to 3 months).

How often does the 3100 unit record data?
The 3100 unit records a data point every second.  If you are using the AA batteries to power the unit, you can always leave it on this default setting.  Decreasing the recording rate does not affect the battery life.

Do I need to worry about filling up the memory of the 3100 unit?
No.  The unit stores 300 hours of driving.  Most likely you will download the data and replace the batteries before it fills up.

Does this unit work anywhere in the U.S.?
Yes.  Everywhere in all 50 states.

Does this unit work in any other countries?
Yes. The unit will work anywhere in the world.  The software includes an interface to satellite imagery for the entire world and street maps for the following countries:  USA, Canada, Andorra, Austria, Belgium, Switzerland, Czech Republic, Germany, Denmark, Spain, Finland, France, UK, Greece, Ireland, Italy, Luxembourg, Netherlands, Norway, Poland, Portugal, San Marino, and Sweden. 

What kind of cable comes with it to download the tracking data?
The unit comes with a USB download cable.

What is the warranty on the 3100?
The 3100 unit comes with a manufacturer's full 1 year warranty.

Do I need to subscribe to a monthly service in order to get this to work?
No. There are no monthly fees or activation fees.  This is not a real time tracking system. The real time tracking systems are the ones that require monthly fees and contracts.  Most people prefer the 3100 for this very reason. Remember, to find out what the driver has been doing, you connect the GPS tracking unit to your computer and it will give a complete history including speeds, locations stopped, and how long they were stopped.

Can I use this system for stolen vehicle recovery?
No.  You need a real time tracking system to do that.  Real time tracking systems are more expensive and require a monthly service fee.

Does this unit have a motion sensor in it?
Yes.  The unit turns on as soon as the vehicle starts moving.  When the vehicle is stopped for more than 4 minutes, it will go into a sleep mode to conserve battery life.
