Depends on what system you have
If its the Hi Fi you can unplug it a the amp . There is an amp connector with
a lever at the amp.
On L7 if you disconnect it you will disconnect the most bus ring which will cause SOS and bluetooth errors to .
If you have a 2010 2011 stereo system I think you would have to pull
the fuse for the radio as it has no amp.
Also alternatively you might look at the fuse map and find a relevent fuse to pull.(behind the glove compartment)
