:DI've look around clarion site and even tried to call, they are not so much in direct cust. service I've looked on the update site and it did not see my card because it did not have a map on it. If I sold it, then I'd have nothing!!!
I got a truck with a Clarion NX702 head Unit. Everything works except the Navigation. When you hit maps nothing happends. I removed the navigation card (micro sd) and it seems blank. What do I need to do to download a map and get the unit to read it?
