Hello Guys!!

Successfully retrofitted my second nbt2, however the last one was having couple of issues, i fixed most of them, except one tiny thing, as i know sth is missing but i cant figure it out.
The car was running CIC with Combox
Rear camera, mic, aux, USB all are working fine now as it needed re wirring.
however, i didn't bring TV back to life, all blue screen, as according to this assignments from ISTA pin assignment



which i transformed to this



TV now gives no signal
PIN 34 38 40 it gave me No signal while audio was and still working.

While in here


Just TRSVC (Camera) and BASEPLATE (SNAP-IN Adapter) present, no TV in the pin out
---

I didn't try to add the TV pins to the FBAS (baseplate) yet, as removing pins from the quadlock is totally irritating, so i wanna some confirmation from you guys!
---

Another issue here, the radio works on AM only, NO FM channels, is there any mod is made in the aerial system?

In case someone needed the original quadlock wirings


and that's it.

---

UPDATE:
When i just drove out of the area it worked, seems to be this new pin out is right.

but still FM is not working, any ideas?

I know that NBT sometimes requires modification on some Chassis.
This is what I have found online(Can't remember source. But I did not write this) and stored in my PDF guide for this type of issue.

"you must detach pin 13 of NBT harness (NBT side) and connect it to a +12V switched source.

The problem is that NBT does not put out a 'radio on' signal on pin 13, like CCC, and CIC do. The radio on signal is used by cars without NBT to power the amplifier, and diversity antenna. If you are retrofitting NBT, and you prior headunit was putting out a radio on signal on pin 13, you need to send power on pin 13 on the car side. The easiest way is to connect pin 13 on the harness/car side to pin 15. Pin 15 is powered with the ignition, so your amplifier, and diversity antenna will be powered whenever the ignition is on."
