I'm sorting things out for my son's 2012 Corsa D 1.2 petrol. This will be his second Corsa as he's a fondness for them, they are nice little cars after all. The first problem he's set me is to fit a aftermarket Android radios from Amazon 🙄 and the first problem I've encountered is setting up the steering wheel controls. There are 2 wires labelled Key1 and Key 2 which are not connected to the quad lock to the cars radio harness. Each time I try to program a button, I keep getting "failed try again". Has anyone else fitted one of these Android and had the same trouble and is so how did you sort it.
