MiCarl Posted April 30, 2009 Share #1 Posted April 30, 2009 I'm going to mount a GPS NAV system on my 89 and think it would be great to tie it's audio output into the intercom system so the NAV will interrupt the radio when it talks. Now, the audio output on the unit is enough to drive headphones so I bet it's way too much signal to tie directly into the MIC input on the amp. Anyone got any suggestions on how to properly make this connection? Link to comment Share on other sites More sharing options...

loehring Posted April 30, 2009 Share #3 Posted April 30, 2009 Cheap fix..... Use a cassette adapter. That's what I did. The only down side is that you need to have the cassette active so the radio won't work when you have the Nav running. For me that was no big issue. I have the Garmin Zumo 550 which has XM Radio and an MP3 player so the loss of the onboard radio was no big deal. Hope that helps. Link to comment Share on other sites More sharing options...
