Received the 2010 MapnSoft update for 2009 Sonata Limited Infinity Amp. When I started the update the first two steps loaded fine and the third step would progress about 5% before receiving an "Update Failure" screen. The message reads "Can't read data file/Deck/common/MAP.spd.000(read.err.30) I cleaned the disk and tried several times and it always quits at the same spot. The biggest problem is that I cannot get my radio controls to show up. Anyone have any ideas. I have a call in to MapnSoft and assume that the disk is bad and needs to be replaced, but was wondering if there is any way to get the radio controls back.
