Hi Willy07,

I have a Cayenne 92A (2011) with PCM 3.1. I will pull the fuse, but is that still necessary after completely disconnecting and reconnecting again (as I did)? Thanks.

Willy07

If you disconnected all cables. then no...that would be the same thing.
In most cases.....a black screen is because a ribbon cable is not making it....or defective....either in the cage or at the display board if that got tugged ?

Hi, all connected as it should I think.

Willy07

From what I can see here...looks correct. If you have not, redo the ribbons., they are the usual problem.....check that they are perfectly flat, and locked in .....check them that the gold fingers on the end are not damaged. If thats all good...you need to contact support I guess.

Willy07

Do not push it back in with the antennas like that...they are very fragile and will break, tape them to the back plane, mine are horizontal and work fine.

Everything…. And when I say everything, was really everything twice or three times…

See my story here: https://www.diymobileaudio.com/threa...de-log.432348/

To answer your question, I have a Umik-1 calibrated microphone and use it with REW (Room EQ Wizard).

Redo the ribbons. You have to get them in just right.

Okay, thanks. I will try again. I think there is no support from Isudar the coming days due to New Year Holidays.

We had the same problems, reconnected everything, make sure that the flat wires with the blue stripes are straight in the connector, so the width of the blue is even across the entire connector.
I had also black screens, we could not believe it was faulty wiring, but it was. Now it works like a charm, no black screens, even the wifi problems solved. (Wifi stayed visible in a wifi analyzer even when the car was turned of for the night).

Thanks, it did work, reconnecting everything. You can't see it looking at the pics, but one connector on the lower board did not fit well. Problem solved!

Nectarin

Thanks for your help. Reconnecting did work afterall.

For now, Too little, too late. Maybe a good idea to send an automatic email to new members with your "instructions"?

Once you get it working, its pretty nice...

There's a missing step with reconnecting the power harness. The first one I received had to be just right to work. The second connected like it should normally connect with no issues when I got to step 10....lol

This is very funny….

however, you forgot a step…. “Pull the fuse and reinstall it”...

That step could be anywhere between step 1 and 9…🙂
