Last winter the BMW 3GT (F34) 20d display device did not work.
If 'Control Display' does not work
I can not see the navigation and I do not get the help of the parking assistance system. It is very difficult to park in narrow parking areas like Korea.

If you need to drive or park right now, open the trunk and look for a 'fuse box'.

Therefore, you can check if you open the 3GT trunk tray.

| Fuse box manual |
1. Opening the trunk fuse box cover encloses the fuse box instructions.
Refer to the fuse box manual and search for 'information (navigation)' fuse.

2. The '121' fuse governs the information (navigation). Therefore, pull out the fuse and check the condition.
3. If the fuse is blown, replace the fuse
If it is not, I will mount it again.
 |
| Information that works again |
When you plug in the fuse, you can see that the information system works well with the sound of the radio.
At the same time, the parking assistance function will be activated again.

Then why? Did the information system not work?
The reason is the voltage.
When we test the voltage of the vehicle, we get about 11.87V
This is probably due to the over-power of the battery as it continues to work on large power consuming devices such as cold winters, short runs, hot wires and black boxes.
 |
| CTEK charger |
The solution is it charges the vehicle's battery by high-speed driving for more than 1 hour and recharges the vehicle's battery by using the battery charger.

 |
| AGM battery |
The BMW 3GT (F34) car has an AGM battery to support ISG functions
It may be a good idea to purchase and use a compatible battery charger.
Thank you.
