Navi 900 to Android head unit

[airainchoc]

Hello,

I recently bought an Android head unit for my 2012 Astra J GTC

It's working well appart from one thing, the central control panel of my Navi 900 doesn't work (no light, no buttons) with it.

Is there a way to rewire it to work or something ?

(I'm in France so can't really come for it to be done, have to do it myself)

Thanks

I think someone may have posted how its done in another thread.
