Got a 2011 FFRR 5.0 S/C came with after marked DTC Android 12.3". In the carton was the old Head Unit and a Retractable Side Step Power Module???.
I am now trying to backbuild to the original Head Unit and use an Invery Airdual Bluetooth.
Got all the plug and play connectors of the Android out, original Head Unit back in, dash and panels all back. Head Unit gets light on all the buttons but screen off and rear camera does not respond.
Cannot find any loose connectors. I live a couple of 100 km away from nearest city to ask any Installer Company for advice.
Does any of you guys know which connector I might have missed?
Thank you, I am sweating.

Maybe that is why it was replaced.

You can play Bluetooth music on an Android head unit... Pete

Thank you. That is a very valid point. After another 2 hours of trying all connectors i found a looped fibre optic plug that goes into the top of a module behind the glove compartment fuse element which had to be dropped first to reach the socket. The Head Unit sprung to life and played music via the Invery Airdual Ipod connection. Brilliant. As I start the engine music was gone and screen show RANGE ROVER sign only.............I'll find out why, just wait. Reason I want to back build though is the design and layout I find very unfitting to this car. Don't like Chinesium anyway and the sound is not nice. Controls are hidden in menus that don't make much sense and quick volume control only via steering wheel.
No. I want the old unit back and connect the music app via the Invery Airdual dongle which by the way has become much cheaper. Works great in the 2010 Disco 4.

Sounds like you are getting there then... Good luck

 Pete

Thank you Haylands,
The head unit is now working and the logic7 is just fine for my 58 years old ears. I am super happy to have found all the connections. Only thing not responding is the Bluetooth phone connection although there is red light coming out of the module in the right side of the boot.
Will figure that out too and keep you updated. Fingers crossed. And the Invary Airdual is really great and responds the moment you start the car. Awesome
