Basic Wiring Question of OEM NAV in Non-Nav Si

yodaboy · 07-09-2007, 12:28 PM

I just had a "simple" question regarding the installation of a OEM Nav into a Non-Nav Si.....

If I don't care about the whole microphone/steering wheel/voice setup (as I don't even use it in my wife's Nav Civic - Yes Civic family), will the OEM nav just plug in and play? I figure the power, speakers, and basic steering controls (volume and channel) still work the same

I've got the GPS antenna, headunit, and bezel/brackets ready to go, but just wanted to make sure that Honda didn't swap hot wires in the two different wiring harnesses (would be an expensive mistake). I guess the more obvious question is if all the connectors are the same shape/size/configuration as well?

its a differnt harness...it seems you do already have everything except for the navi instrument panel harness...

if you ge thtat it will all be plug and play...but be sure to set out a FULL day put the new harness in as it has some tough spots to get to.
