Remove positive battery terminal from battery & put a 12 volt test light in line between cable & battery post. As long as 12 volt light is illuminated, you have a draw. Start pulling & re-installing fuses, one at a time,until you see it dim or go out. If it goes out, you found your draw. If it dims, slight draw, such as radio memory etc. if all else fails, make sure you know where they all go, then pull them all, and start putting back one at a time. When light comes on bright, you found the circuit causing the draw.

Hellokrissypoo4...Your navigator has what is known as a parasitic battery drain...meaning, something in the vehicles system is not turning off...here is the way i test for this, you will need a digitial multimeter to perform this test...when doing this test make sure that the dome light, under hood light, trunk light, etc. are OFF.

I would first have the alternator checked by an auto electrician to ensure it is working correctly and is providing the correct volume of current. It may be faulty and when driving you will be drawing battery power instead of power from the alternator to run the electrics. This will drain the battery.
Alternators do not last forever and if you are still running the original unit it is likely to be on it's last legs and you will need a replacement unit.
