E90 sat nv problems

alf1956 · 06-24-2018, 02:31 PM

Hello I have just got a 2010 3 series BMW 320 diesel which has a built in sat nav but when I try to go onto the sat nav it comes up with a "no signal" message. I can see that there is a micro SD card in the sat nav slot to the bottom right of the sat nav/radio, I have taken out the SD card & put it back in but it's still the same. I don't have a manual for the car so I cannot refer to it to see what the problem is but I am hoping to get one next week.

That sounds like the Sat Nav antenna is disconnected, the antenna AMP is not working or the TCU/MULF is not connected properly.

You should post the last 7 numbers of your VIN so others can see what the default equipment is in your car.
