F20 Hu Entry nav to NBT EVO, GPS no signal

F20FAN_283 · 02-02-2024, 05:28 AM

Hi I have read all the treads I could manage to fix my problem but with no luck.

I have fitted the new NBT evo and installed maps with Fsc codes But the gps is over a 1000km from where I am and in the secret menu gps signal says restricted.
I got the following info from Ista to help identify the issue:
Status of registration of modem: Not defined
Signal strength of mobile network: 0
Fault cause in the communication of the hypertext transfer protocol(HTTP).

My Car has a TCB unit.
I have tried all the coding options regarding the GPS and Telematic unit with no difference.

Only thing I can think of doing is I have to check the cables behind the HU and do some more testing in ISTA and see if I have contact with the TCB unit. I am a bit confused if I should have the GPS coded to use the TCB or have it not inactive, I have tried both with out any difference.

So I was looking behind the head unit and it turns out it doesn't have a GPS plug which is strange because the car it came from had navigation. How do I make my navigation work with out a GPS do I Need the TCB module to be connected to the car to get GPS signal and connected drive?

This is how it looks behind my head unit now. I have the blue which is the GPS I believe and the Green which goes to the TCB.
