Q: What is BMW LVDS?
Re: On the back of original display, there is one connector connected to the original car monitor, we call it LVDS.
Original LVDS (Example)
What kind of LVDS BMW Radio Head unit contains?
There are three kind of BMW LVDS connector: 10 PIN, 4 PIN, 6 PIN, it have some relationship with the original BMW System (CCC,CIC, NBT, EVO)
When you replace with our android screen, you need to insert the factory LVDS to our model, so that the original car functions can display on our android screen correctly.
Why to check the LVDS ?
In order to confirm the car compatibility, sometimes need to check the type of LVDS (4pin/6pin/10pin etc), especially when the produced year of your car is just in between the two car generations.
Here is one example: one of our customer have the BMW 1 series F20, left hand drive,car model from 2014,and he offer the photo showed as below
As we know, the car produced from 2013-2016 should be NBT System (6 pin LVDS), but his car is 2014 with CIC system, as we know the CIC system should have 4 pin LVDS.
In this case, it need to open the dashboard and check the factory LVDS connector on the back of factory screen, to see it is 6 PIN or 4 PIN. After talking with customer, he open the dashboard and offer us the photo, it show 6 PIN, thus,we recommend our B211 to his car.
Some friends might feel that is too trouble to open the dashboard and check it's LVDS, but for this special case, this is the only way to check the car compatibility. But this is just exceptional case, it just about 1%~2% case that need to open the dahsboard.
Most of time, we just need to get one photo of dashboard (with the factory main menu :ccc,cic,nbt,evo), then we will know the car compatibility.
