Hey everyone,

I am taking on a new project which is to install an aftermarket head unit into my car whilst keeping the original stock head unit for the climate control settings/clock.
How exactly would i wire the two head units together?

Additional info: Honda accord euro 06- installing double DIN head unit into glove box.

 

Transfer all the speaker wiring to the new deck and leave just the batt/ign/ground/data on the factory one.
