Instructions 2 of 2
Head unit removal
6. The aircon has a blue adaptor with a black hook (maked in red). Lift the black hook and the adaptor comes free.
7. Now the back of the cage is visible. 4 screws in total hold the cage in place. remove them.
8. If you have a black box at the bottom of the cage (marked in red in instruction set 1), that is your Blue&ME unit. This also has blue adaptor with black hook. remove it.
Regardless of you using blu&me or not, this unit has to be plugged back in otherwise your 159 will throw you CANBUS error by way of making your mileage flash constantly.
As you can see its a bulky unit, and if you fitting in a proper double din unit, this causes issues.
To overcome this, I took out the blue&me from its housing, (clips on either side and top and bottom) and opened it. (4 hex screws). I took out the board which is tiny, carefully wrapped it, plugged it back in again, and pushed it down the side. Worked fine! If anyone has other ideas, please share.
9. Now you can fit your new unit. Which must be fitted with a head unit fitting kit which you would have got from your audio dealer.
and reverse fit all the fascia and airvents.
Sorry last image isnt very clear as it got dark by time i finished.
After fitting, I had a few problems where my alarm stopped working and my mileage was still flashing eventhough i fitted the blue&me back in.
I also noticed my interior ligts were not working and message on dash saying "Alarm not active" or something like that.
This happened because the fuse F39 in the fuse box blew which is the fuse for the interior lights. I replaced it, with the spare fuses provided (10a) and all was well.
I hope this is of help to someone.
Any questions please ask.
