寶馬系e音響機頭拆卸圖解HU removal

1、Now remove the heater controls which again pull out with little force.I found that along the top edge of the heater controls where two plastic lugs which clipped into the dashboard itself.These didnt require any force to remove and in all honesty you can just get your fingers behind the unit and pus

2、h it out uniformly. On either side of the unit were two spring loaded clips that just popped out in this process. (I shouldve photographed these!) I wouldnt suggest pushing anything in from the sides of the unit as I have seen reference to on other guides, using a folded credit card etc. I had one o

3、f these to hand but it wasnt necessary with this method. It may be that the pre-LCI cars have a different fitment. Slight pressure was all that was needed. Once you have it out there are three multi plugs which simply unclip. The centre and right hand clips in the picture have a bracket which you un

You push this to the left of the picture and it releases the black clip.Here with the unit removed you can see the hinge type clip in the background.Once the heater controls are removed the outer plastic trim surro

This is held in place by four long slim metal rods which again pull out with light pressure.There is one multi plug which needs to be unclipped before freeing the surround completely.Next comes the removal of the head unitThis is held in by four screwsAnd simply slide

6、s out after theyre removed. I recommend placing a towel or similar onto the centre console to protect the metal surface from scratches as the head unit will rest here whilst youre fitting the centre speaker and harness and it has a metal frame.Once pulled out the connectors are visible at the bottom

7、 left hand side.Non-idriveYou will find on top of the AC contorl two gaps if you slitghtly push the plastic cover outwards. Insert a screwdriver inside them and press down an pull out at the same time each at a time. It should come out with a bit of force.to remove the radio (non-idrive), follow the

8、se instructions. Don't pull from the top! Use an old credit card (or hotel room key), bend it on one end, so it makes an L shape when viewed from side, then stick the bent portion behind the panel and slide it down the side as far down as you can, and then pull forward with the credit card. One

This is fastened with two clips on the sides:1. take an old creditcard (or something similar) and bend one (short) side of it in a

Repeat step 3 for both left and righ

11、t side.5. you should now be able to pull the a/c controls forward. Then you can remove the radio:use a screwdriver to remove the two screws beneath the radio and pull the radio forward.Some pictures to clarify the way the A/c controles are snapped in:Keep the bent portion of the credit card very narrow, probably a few milimeters:Work the credit card down the side as low as you can get it:Once it's there, rotate it up and down around an imaginary axis piercing the center of the card. That's what finally did the trick for me. I hope this adds some clarity. I will
