i got a DVD Player with in built GPS tracking system and I want to install advanced navigation software of GPS which I will use for my perosnal work....is there any gps software which i can get it installed for my player ? I dont need live data facilty....just to monitor the car moves......

Can someone suggest me a cheap GPS system so that i can get some relief from my petrol expenses..without proper monitoring, my fuel tank is lost everyday with unusual motoring..
