After installing the AV Navigator CD on my laptop computer.running Vista and Windows 8, the "Wiring Navi" section does not contain any text. Only diagrams and the radio buttons. Without text it is impossible to interactively setup my VX-1121k receiver. Isn't the "User Account Control" box supposed to appear in prior to the Wiring Nuvi section loading?. Don't believe the problem is this CD since will load correctly on a computer running XP.
