Nav Retrofit MPG Info

[JonnyC]

Hi

I am currently trying to attempt the X5 Nav Retrofit (including wiring harness) and am following the guide by JPuma.

I am a bit confussed as to how the MPG info etc (which currently is displayed on my business radio) is sent to the 16:9 screen etc, is there a connector that I have missed or a method to sort this, or is this not possible

Thanks for your help

Jon

Also if anyone can answer a previous post of mine it would be greatly appreciated as i am a struggling newbie with X5s, please see below link
