Hi I picked up a 2014 Mustang GT 2 weeks ago Tuesday and it has an Kenwood dnx571hd installed and it has 2014 maps installed I found a YouTube video showing where and how to download the map for free which I did but it's not showing up all the stores etc like GPS on my Galaxy does. My question is if I buy the $75 update will it have all the locations or be like the free update I downloaded and missing some stores like Walmart Neighborhood stores?
