Radio FM/AM issue after NBT Retrofit
Hi everybody,
After I made idrive Business to NBT retrofit on my F30, I have an issue in the radio stations, nothing works. Neither FM nor AM works, I tried to connect car antenna connector to black and white NBT connectors, I had just very poor signal and one or two stations with bad sound quality I have found this link which describe a DIY tutorial of the similar issue: http://blog.diyobd2.fr/diy-e60-nbt-r...rsity-antenna/ Someone had this issue ? did this tutorial ? |

Unfortunatly, it doesn't work..
Maybe my diagram is false, or NBT needs absolutly amplifier (65 20 9 231 174) to get a good signal quality Hope get your feedback |

I came across this post, when I was looking for something else. I know this is an old post, but it doesn't contain the solution (and more importantly contains incorrect information), so I decided to post to it.
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. |

I spliced using chocolate block cables 13 and 15 car wiring before the quad lock that you would plug into the head unit ( car - splice - quad lock - emulator - nbt ) On my car it was a black thin cable and a green yellow thick cable. I actually meant to take pictures but was freaking out due to a botched cut on my ceiling mike!! |

But I wanted to ask if you have pictures or video of what you did exactly because I am confused. If I cut the cable that comes from car and goes to pin 13 and cut the cable that goes to pin 15 and then connect these 2 then it means the cables pin 13 and 15 no longer go to headunit. Or should I actually cut 15, put a chocolate block in between to let 15 continue to NBT unit. Then cut 13 and squeeze it in the chocolate block of 15? Do I see which number the cable is on the emulator? If anyone has pictures or a video I would be so grateful. |

If you had CIC, the CIC headunit would output 12v on pin 13, which would power the diversity antenna. The NBT headunits no longer output 12v on pin 13, so in order for the antenna to be powered, you must put 12v on pin 13 from somewhere - the lighter is often used. You do not want to send 12v on pin 13 into the NBT headunit, so you cut the line.
So, for pin 13 in the quadlock connector, it should not be connected to anything on the NBT side, and it should be connected to a switched 12v, like the lighter, on the car side. This will power the antenna when the car is on, which will allow you to receive reception of stations.

You are correct i think, it worked then i bridged pin13 and 15 and i tried to rewire pin 15 to pin 13 (which didnt work) so what i need to do is to pull pin 13 and isolate it, so that it's not connected to the unit.
