DIY Radio hidden cookie menu
Since this comes up from time to time… I thought I would post this. This will allow you into the hidden radio menu’s. I do not know what all is in there. But you can cycle thru each screen and check it out for yourself.
I first got interested in this because I have a US spec car in Europe. So I made sure I switched the radio over to ECE code and also to make sure the Antenna diversity was switched to “auto” mode. I think the antenna switching might help out a lot of 1er’s that have some reception problems.
Btw…. My 135i is a 2010 US spec with the base radio and no Navi.

Ok here is how to get access to the hidden menu’s…
#1, put the key fob into the slot. Make sure the radio is OFF.
pic of my radio off…
#2, switch the radio ON, and then press and HOLD the “M” button just bellow the volume/on knob.
Turning the radio on…
NOW immediately press and HOLD the “M” button in… keep holding it….
This is what the screen will look like once your in the hidden menu…
Main menu screen – “Device Functions”…
scroll down one screen…
ECE = Europe, USA, JPN = Japan, OCE = ? Maybe “Other Countries in European” ?
Scroll down a screen…
Next screen…
Next screen…
Next screen…

The antenna selection screen…
Note: when you make a change the radio will save it automatically. IF you want to exit the hidden menu… just turn the radio off and then back on.
Good Luck
