They are just telling you that because they want you to drop $200 on the OEM discs they sell. I have been using burned discs in my Nav since 2007 without any issues. The only issue, if you would even call it that, is I burned a bad copy once (burned it at too high of a speed) and it took a long time to pull up addresses when I was inputting them. Other than that you shouldn't have any issues.
