Hi I am looking for the most user friendly real time gps tracking
system to instal in an automobile. The ones that I have purchased have
had a 5 minute delay between actual location and time its relayed. I
have a need to know where the vehicle is in real time. I would also
like a very clear map and or locator to let me know its adress and
location. I would prefer to have the kind that instals direct wired to
the automobiles power supply as apposed using a seperate battery that
only last a month or so. I also need geo fencing so i can get an email
when the vehicle enters and leaves a specific location.

I would like a few choices if possible. 

Thank you.

Dear Santarosa,

I'm a developper of GPS Car navigation system.
Can you tell me in what part of the world you are ?

I recommand you the Alpine navigation system if you are in Europe.
They have a very precise map for commercial systems, and the locator
is updated every 100ms. It is very accurate because it decides its
position not only from the GPS signal but also from the speed sensor
(if you connect it) and from dead reckoning with a gyroscope.

bakajo.

Check all kind of gps here.
