Codeigniter - Google map Implementation

[eluser]Unknown[/eluser]
I am using codeigniter 2.0.3 version and I use vehicle tracking using GPS and android device.
My device will send the locations (cordinates) on every 5 minus and need to store in db.

I need to display the exact location in the google map and draw the diagram(route)(I need to link all the location based on the lat and long) Can any one help me out on these ? Any idea how to implement this on Codeigniter ?
