Smart Alex Posted May 22 Share Posted May 22 I am retrofitting an RNS-E to my A4 B7 which is going OK as I previously retrofitted an RNS-D to an A4 B5 znd got it fully functional, even my local Audi dealer was impressed. This time I am a little confused by the Navigation/TV tuner. What does it do for navigation as I have no interest in TV in the car. If it serves nothing useful for the navigation I am tempted to use the connector on the head unit for an aftermarket bluetooth music interface. The CD changer connects direct to the head unit as does the GPS anttena. Quote Link to comment Share on other sites More sharing options...
