Does anyone know if there is a way to get the stock Nav to work with a aftermarket radio in a 1997 RR SE? As far as getting getting the voice to play through the speaker again? The Nav still works just no sound. Thanks

 

There is so many variables with aftermarket radios, each with their own configuration of inputs and such that you probably need to refer this question to someone who knows your radio. The free downloadable shop manual has a wiring diagram for the stock radio and nav system which will help. For instance, some radios have an input for a cellphone that allows it to interrupt the music when a call comes through and many don't.
