Navigation Disc Help

[BigDawg99]

i just bought a 07 HUmmer H2 and it never came with the Navigation Dvd...I have the Luxury cd Player by the way...I went searching online and downloaded this ISO File from the internet and it said to burn onto a Dual Layer Dvd Disc..i went out and bought a Vervatim 3 Pack and tried to burn this ISO file onto the Cd...I have a Toshiba Sattelite L505 and it burns DL..I have tried 2 Cds Already and when i put it into the Cd Player..It says Disc Error..Its not reading the Dvd with the navigation Program on there...Is there anyway that i can get this to play..I just bought the HUmmer and dont have another 200 to pay for a Navigation Dvd which should have came with the Beast....Any help you can give me would be awesome and Much APpreciated..
