When you are looking for an aftermarket BMW E60 android head unit, the first thing you need to find out is if your BMW E60 has a working AUX or not.

Factory AUX is very important for BMW E60 if you want to do a head unit upgrade. It doesn’t matter if your BMW E60 has factory navigation or not, but aux is important, why?

Because the sound transfers to your car speakers through your car’s factory aux mode. This is what all aftermarket units use to resolve sound transfer issues for the BMW E60.

That’s is to say, if your BMW E60 does not have AUX function, there will be no sound after installation unless you get a small amplifier which connects to your car speakers to transfer the sound, or you can coding aux from BMW.

2 Steps Tutorial: Find AUX on a BMW E60

Step 1: Find AUX Location
 

Firstly, for the BMW E60 with a factory-installed AUX, the AUX port is usually located at the back of the car’s armrest, see below picture:

Note: for some BMW E60, your aux may be in the armrest.

Some E60 owners installed AUX below the radio system as this picture showing:

 Step 2: Find AUX Screen Menu

Besides an AUX port you can find, you should also be able to enter AUX menu option from your factory screen menus:

This AUX option should not be with grey color, and you should be able to enter into AUX mode, please check below picture showing the normal AUX mode:

Besides, if you connect your phone with an aux cable, the music sound from your phone can come out from car speakers.

Overall, if you are able to enter into the aux mode as above and can play music with your phone via aux, that means your car has a working aux.

Solution for BMW E60 without AUX

My BMW E60 does not have AUX function, can i still install an Android screen unit?

That depends on, if you can make sure your car does not have aux function and not with a fiber optic amplifier, you can still install an android screen unit. Just remember to buy a small amplifier together with the unit to transfer the sound from the unit to car door speakers.

Because if your car has a fiber optic amplifier, the add-on small amp does not work with the factory fiber optic amp.

So the next question is, how to check if my BMW E60 has a fiber optic amplifier?

You can try to take out the factory radio/CD unit, and check a big plug behind, if there are 8 speaker wires from the plug, that means your car does not have a fiber optic amplifier.

See this photo:

Our small amplifier connects to your 8 speaker wires from factory wiring harness(behind the radio/CD) directly to get sound, so the sound does not go through factory amplifier or subwoofer if your car has it. By the way, the sound quality may not so good compared with the sound quality from radio or CD if your car has more than 4 speakers or amp or subwoofer.

Additionally, you can also use a FM transmitter to transfer the sound from the new unit to car speakers.
