Hello,

I retrofited Nav pro and Video module (for RVC) in X3 E83 2004. The car come with Nav business.
Harness home made.
Coded $609 and $601.

Problem, screen display nothing. I thought the LCD panel was broken but when I do the self-test of the video module with INPA, the screen shows color lines "RGB-Test LOEWE", see attached picture.

Is it a coding problem ?

In TV2.C02, there is some parameters "Widescreen", value 0, 1, 2, 3, or 4....?

Someone has TRC file of TV2 with nav pro ?

Thx

I tried with an other MK4 and now it works fine

May be they are differentes version of MK4, business, pro... ?

Wiring diagram coming soon

Next step, reverse camera on video module

Hi stecom90,

Thanks very much for your post. I would like to know a bit more on your progress as I might have a similar issue.

In my case, it is a E83 from 2010 with the Professional Radio. I would like to add a reverse camera to start with, but also to see if I can move from DVD based to GPS based navigation.

With thanks,
