Help with no GPS signal in newly bought F30 which has a retrofitted NBT EVO ID5
Hello, I have bought a 2016 340i F30 LCI model, which has a retrofitted NBT EVO ID5.
The problem is, the navigation has no GPS signal (just shows the location somewhere in the ocean near Ireland, while I am in eastern Europe) and I am trying to investigate why is that. I have made some research about the NBT EVO head units and found out that some of the head units use a GPS antenna connected in to a blue connector in the head unit and some only use the connection to the ATM module. Is there any way to figure out which connection do I need for my NBT head unit before ripping the HU out? Also, is there a way to figure out if I even have ATM module installed into my car before I rip out the internal headliner of the car? Update: I have no ATM unit, only TCB. Also, the car has working Apple Carplay. Update: Now my main questions are:
I am able to code with Esys pro My NBT version shown on screen is: View post on imgur.com Last edited by Pauliuslau; 02-02-2024 at 03:52 AM.. |

If you truly have a 2016 vehicle, you should have an ATM.
A professional coder should be able to change the coding which tells the HU to look for the GPS Signal on the OABR plug via the ATM instead of the blue Fakra behind the dash. If a GPS plug to the ATM isn’t there, you might need to run a 5 meter GPS Fakra extension from behind the dash to the ATM in the rear, but every 2016 already had the GPS wired to the ATM in the USA, afaik. Even the NBT-EVO HW 1.x units in the 2015 M235 models had the GPS wired to the ATM. Contact kubax86 to help you out with the coding as he’s almost a local to you. |

So I have inspected my car further and I have found out that my car has a TCB module instead of ATM.
I read the Navigation codes with E-sys and they are as follows: GPS_FROM_NAVI --> aktiv SYSTEM_RECEIVER_GPS --> nicht_aktiv TELEMATIC_ECU --> tcb Do I need an ATM module in order for GPS signal to work? Would I need to code it? I only want the GPS signal, no other SIM card related services. This is my TCB module: View post on imgur.com Last edited by Pauliuslau; 02-02-2024 at 03:43 AM.. |

No ATM is needed for ID5 unless you wish to use GPS and Connected Drive Features. Otherwise a workaround is needed if you want to use these options. |

What if I need only GPS and no Connected drive. Do I must have the ATM for GPS and there are no workarounds? |

I am aware of someone working on a much easier/cheaper retrofit as apart of replacing to TCB devices, but it’s a hobby that they are working on at their leisure. On another note, thank you for the production date. It sounds as if the EU cars must have gotten the ATMs in the F30 later than the USA cars, which is strange, because EU Cars used to be about 6 months prior to USA in the HU/TCU systems. |

What about replacing the TCB with ATM? Would that work for GPS signal only? |

Prior to NBT EVO HW 3.x, the GPS was wired directly to the HU, even though ATM equipped vehicles were run to the ATM as well. Running only to the ATM in the trunk/roof keep an additional coax cable from needing to be run to the dash. |
