Hi all,

I burned a DVD+R of the v2007.2 DVD NAVTEQ disc and my current 2004 MkIV DVD system kept rejecting the disc. Is it because I need to upgrade the NAV firmware? I'm not sure what version the firmware is, but I don't think the previous owner updated it since getting the car in 8/2004. I searched in the forum, but couldn't find the answer. Anyone have any tips? Also, i was having trouble burning the v29.1 firmware onto CD. kept getting sector errors on the burn using ImgBurn. Thanks.
