The most easy stright fit cable for a stereo upgrade, I used for my Vauxhall Zafira 2010 and was easy plug and play no need to connect a power cable as the box does everything for you just plug and play, my steering controls work perfectly.
I would highly recommend this cable for a stereo upgrade.
Excellent seller fast delivery five stars all the way.
I initially bought a connects 2 interface which only came on with ignition. This is far better as it functions as per original Vauxhall radio where it only turns off when key is removed. The steering mute also functions properly. Very good product
