Tonsoffun_87 Posted December 16, 2011 Report Share Posted December 16, 2011 When I go to software information under the navigation tab, it says no data on disc. how can that be when it is on the navigation map it shows the current streets around me, yet when I type in an address it says cannot calculate route? Does this mean I have a bad head unit, or a messed up disc? Please help tech guys. Quote Link to post Share on other sites
