I have had periodic volume spike issues. seems to be a poor design of the cable that runs from the front panel to the enbt adapter.

black screen issues I think there is a power saving option that needs to be disabled if your evo is running anything newer than 2018-03 and you have a non-evo screen.

My NBT EVO is from 07/2018 and I'm indeed using an APIX1 screen with voltage regulator. Any Idea how to disable that power saving option?

Look in the coding for this option:
DISPLAY_PIP_CONFIG - DIMMUNGSVARIANTE
change that from "neue_dimmung" to "alte_dimmung"

I have not tried this myself, but found it on one of the cartechnology threads when I was researching the problem a few months ago.

If that doesn't fix it, you can flash back to 03/2018 software. I did that on Nick's evo and he hasn't gotten black screen / no signal issues since

I'm not really familair with flashing etc, will figure that out then.
Does the black screen issue only occur by using APIX1 screen, or also with an APIX2?

It only happens with APIX1 screens and with firmware starting with 2018-07.

You need to tape the ribbon cable to the trim in one or two spots to stop the volume jumps.

Thanks!
I did solve the problem of the black screens, but without flashing older firmware.

I bought an X3 screen (latest partNo.) Which is APIX2 and I modified it a little bit to fit in my e8x housing.

Problem solved an having better screen quality now


Still having two problems with the EVO, which both have to do with coding.
1. EVO forgets what was saved under the favorite buttons every time after coding.
2. Every time after coding the unit reboots, but I'm not able to connect again until I wait until the car goes to sleep. DHCP problem?
