I would like to replace my factory head unit and install an amp and head unit I already own. How would I handle the output of the NAV through the Stereo? Currently I hear the NAV voice cut into my music as I listen to it. Do I have any Head Unit options ?

thanks !!!

 

There is not much more you can do, but have the nav mute your headunit and run the nav output back to one of your amp and use a y adaptor. The output of the nav is just a low level output signal. No aftermarket headunt can handle the output of the nav and play your music at the same time.

I agree. The headunit I have has a audio interupt, so when the signal comes across it does a 20db mute. Most guys put a speaker in the center near the headunit for the audio, or you can run it to a small amp on its own, but it might be loud if you have the gain turned up on the amps.
