Just bought and installed one of these:

Ordered the higher RAM/CPU spec for £218. Arrived in 6 days from China. Looked a bit bewildering at first, but they sent me installation info and the wiring was pretty much plug and play. What was important for me was keeping the reverse camera in the top screen, and steering wheel controls working. I could configure the steering wheel controls to do what I want in the interface, so I now have a mute button on the steering wheel too which I hated not having before! (I used the 'speech' button).

Here it is in action with Android Auto. There are a lot of apps/features without connecting your phone, they work fine too. In this image the top looks to be protruding a little, the clips are not all in place yet at the top, I think need a slight bend to make stay home, looks easy enough to sort. It really works well and doesn't look/feel too large. The interface is fast and the touch screen swipes quickly. Wireless Android Auto works fine (but they also supplied a USB connection/cable for wired which easily connects and comes through into the glove box). Will take some more photos later.

RX Saloon 400 H · September 4

Bonjour,

Merci pour cette présentation.
J’ai acheté le même poste que vous, en revanche j’ai les problèmes suivants :

- l’écran au-dessus de l’oridinateur de bord n’affiche plus les informations de
la gestion d’énergie
- Plus d’activation de la caméra de recul lors de la marche arrière
- Plus de son dans les enceintes arrières !

Pouvez-vous me dire ce qui a été mal fait ?

Merci pour votre aide .

Google translate:

- the screen above the on-board computer no longer displays the information
energy management
- No more activation of the reversing camera when reversing
- No more sound from the rear speakers!

Hmm my top screen still works properly, as well as the reverse camera and speakers. Maybe you disconnected something more than needed? If not I think your issue may be due to the need for a resistor between two pins/ports on one of the connectors (this was supplied with my device). If you talk to them online they will answer quickly and support you. I had a few questions and they sent me a WhatsApp link and were very helpful.
