Yes that is what I understood, but when you say ATM active, you mean the subscriptions are valid? I don't think I will extend my subscriptions. My only concern is that GPS works after subscriptions are expired and no SOS error.

Now that the new X1 has NBT EVO and ATM, maybe BMW would accept to sell ATM with my original VIN? I have 2016 X1 model which had TCB.

If you don't care about subscriptions you are all set. SOS errors can be coded out with -TELD.

 

[sylphide]

I already tried to code KOMBI with TELD (cannot add "+" or "-" before TELD in HO-WORT using esys)

Error is still appearing.

 

[2real4u]

Code the ECU that's throwing an error in ISTA, Tool32 or INPA.

 

[sylphide]

OK thanks I will try that next time it appears :thumbup:

I just hope it has nothing to do with HU_NBT2 because I cannot code this one. It would break the whole retrofit..

 

[larry_bml]

Yes, in Kombi, mine is an F30, yours?

 

[sylphide]

Yes, in Kombi, mine is an F30, yours?

My unit is from F25.

Did you test other parameters before finding cc_Aktivierung_5? Are you sure it does not disable other functions?

 

[sylphide]

OK I tried cc_Aktivierung_5=aus and SOS error is gone but it generates at least 3 new important errors in ISTA so I reverted it back. Are your counters still working on your dashboard?

My original error is "GPS aerial: Open Circuit" with details "A short circuit to B+ of GPS aerial was detected by control unit". The error sometimes disappears and comes back after a few weeks... Very tricky.

I also have another error with oxygen sensor that won't disappear, don't know if it is linked or not with this other problem?

Any idea?

 

[larry_bml]

I realy don't think that cc_Aktivierung_5=aus cause that problems, it is something else. What model of ATM do you use? and what GPS antenna? I manage to use an roof ATM with my car's original GPS antenna, and no errors. Maybe is aerial antenna that gives you problems.
Oxygen sensor also has nothing to do with ATM or kombi coding.

 

[sylphide]

Well I ran a test with ISTA before coding cc_Aktivierung_5=aus (only error was this B+ problem) and just after coding it I confirm I had new errors (kilometer counter error and 2 others). Then I coded back cc_Aktivierung_5=ein and another check confirmed that only B+ problem is present. Did you try a compete test with ISTA?

From what I remember original GPS antenna from X1 F48 is used with ATM from serie 4 (2016). What is really frustrating is that this error disappears with coding in ATM/KOMBI, and then with no apparent reason it keeps coming back.

Do you think I should still search in ATM FDL code or try to replace the antenna?

 

[2real4u]

I think you need to sort out your issues with antennas first - these are hardware issues. I have an ATM working with E60 antennas (Sharkfin and rear shelf) with no errors.

 

[sylphide]

Thanks I think it is my best option. I was not sure if it was hardware because error pops randomly every few weeks, and everything works in the mean time.

 

[2real4u]

You may have a bad contact somewhere in the signal path

Hi there,

Short question. I am retrofitting G30 atm and evo unit in 2010 F10 with can emulator. The ATM is can4 (as per G30) and my network on emulator side is CAN2. Will this cause problems? Anyone experience with this before?

Thanks

ATM on NBT-HU

Hi all, i found this thread about atm retrofit, maybe someone can answer me few questions.

I recently have 435i 15plate .
The situation is, i bought car from auction with stolen NBT Evo, all wires and antenas from Navi in dash was cuted.
I bought NBT HU from ebay with precoded VIN for this car, everything connected, only one thing not working is GPS.
I'm researched that may car have ATM, were Gps signal going trough ATM, and then trough ETH two wire shielded wires goes to NBT HU.
I compare NBT Evo and NBT Hu connections from ATM.
Nbt Evo Have A42*3B 20pin connector, Nbt Hu A42*3B 12pin connector.
I connected ETH wires from ATM acording wiring diagram :
ATM(A331*1B) 2 < > 4 NBT Hu (A42*3B 12pin)
4 < > 2
3 < > 8(shield ground)

Also i changed coding in NBT-HU Gps receiver from navi NICHT Active.

Now my questions:
1) Maybe it's not possible to connect NBT HU with ATM?
2) If it possible, maybe i'm missing something, coding?
3) Think to try reflash with ISTA, can it help i'n my situation?

Thanks , who can help ! )

I believe the 12-pin connector you are using is for additional video sources. For NBT-HU the GPS antenna is connected directly to the back of the NBT headunit - the blue plug. For NBT-EVO, the GPS antenna is connected to the ATM, and the ATM is connected to the headunit over ETH the OABR connector.

The ATM handles both telematics, and GPS, for the EVO headunit. For the older NBT headunit, telematics comes over a 4-pin HSD connector between a TCB (telematics control box), and the green connector on the back of the NBT headunit - TCB had no GPS functionality. I believe this was probably a design change, so that with the antenna directly connected to the telematics controller, it could always no the cars location, it did not require the NBT unit.

Thanks for the answer. One guy Bubblebeard2011 from this forum pm me and told to connect seperate GPS antena and drive few miles to satelites detect me. It worked. But then i try disconnect GPS aerial and it still showing my location without any pluged aerial to gps plug on headunit. The coding is still Gps from navi ACTIVE.
I asume that headunit get location trough can from ATM.
But what interesting that my NBT HU lower generation than EVO and it understanding that info from can bus.
And another thing. I get that NBT HU already precoded to car with my cars VIN. Maybe they changed or flashed software on that headunit?
Because i'm only soldered cuted wires without any VO coding or nbt flashing with Ista.
It's very strange and i want to know how it working in this situation.

P.s that antena from ATM A331*4B white plug. For what it used? Because i left it unpluged.

ATM sends GPS signal over OABR and not CAN. Did you drive without the seperate GPS Antena and it still gave your location, I would find that very odd.

Not sure on your other question, if NBT is coded to your car then it is logical it works if all connections are soldered.

Not sure what 4B plug is, but ATM has two connectors, one for SDARS or DAB signal and one for additional telephone connection. But again not sure what 4B is.

Cheers,

 

[Dododo]

Yes i drive around 5 miles without connected Gps antena and after that put another adrees to navigate. And it all showed. It's very strange

 

[Mashman]

You are NOT getting GPS data over CAN, and nothing is going from the ATM to the NBT-HU.

What happened is that when you connected the GPS antenna, the NBT was able to attain your location. When you disconnected the antenna, the navigation software started to use data from other ECU's such as steering angle sensor, and DSC, to know when you turned, which direcction, and how far you traveled. It only appeared like you were still getting GPS data. This allows the navigation system to work well when in situations where the GPS signal is not reliable.
