So if you can get phone and rear camera on the sat nav screen by cutting a wire can you not just change the settings so you don’t have to cut anything?

No


What age car have you got

O6 rrsport

Surely if the screen has the plugs in the back you should be able to use them

Sadly not

There is a test screen where you can see a small picture.

Do you have a gap iid ?

Yes

If you have a camera connected you can try this to see a mini picture. (select video inputs test)

&t=200s



OR upgrade to a facelift screen with later nav and easier camera input (gap IID required)

Would I need a new screen or can I just change the programming

Option 1 program the Ccf to say rear cam fitted.
Unplug to yellow loom in the display to the front panel and connect camera.
This will give you an idea how the display will work.

Option 2. The link. Requires a replacement screen and other
Bits. Maybe £150

If I changed to a later screen would that have the heater control?

No.

But your can buy remote controlled fbh starters for £85-100
Or £300 for a one you can txt to start it

Ok so now the Bluetooth has disappeared and when trying to reflash with iid tool it fails comes up with E4 fault code and then loads of faults in the future
