After market Head Unit


Registered User
Sorry if this has been asked before. I have searched and not really finding the answers I'm looking for.
I going to be fitting a new after market touch screen HU but need to know what all the wires do on my standard HU, as I wouldn't want to loose my steering wheel controls etc.
Thanks in advance for any help.
Pic attached is my new stereo wires.

Easiest fix (cheating maybe) is just to eBay an adaptor harness!
Do you have Bose? The wiring is different and the speaker impedance is also different. Although, many people have run Bose 2 Ohm speakers from aftermarket 4 Ohm head units.
