Anyone having issues with the navigation? I finally had the U73 recall done last week, and now the navigation is lost. turns when it wants, has me positioned nowhere near where I am. Dealer has had the van for 3 days, unable to resolve, and now apparently unable to respond to me. Unfortunately this popped up in month 13 of ownership as I'm nearly at the 30 days but WI only allows problems in the first 12 months for lemon law. Dealer seems lost, claims corporate tech service isn't returning calls or email.
