Hello everyone! I have a 2004 Accord EX with navigation. I’m trying to replace it and was curious as to what the connections on the back of the Navi unit are for. Can anyone please help me understand what each connector is for? I numbered them in the pic to help reference. Thank you very much!

You almost have to look wire by wire in the shop manual. Generally speaking:

1 navigation
2&3 HVAC
4 5 & 6 Audio

 

Appreciate the reply. So I just bought this Accord and the previous owner kept the OEM radio with navigation and installed a touchscreen radio. I removed the OEM radio and I’m trying ti install a Scosche ITCHA01B. But when I connected all that matched I was left with a few connectors so I was wondering what they were. I included pics. Thanks again!




I’m not sure what these two are for.

The black connector is left out. So if it’s for navigation that would make sense.
