E93 unit in boot - what is it?

Hi guys,

Have had my E93 for 5 days now, and loving it! Could someone please advise what this unit is in the boot?



Also, what are the unused connectors for?

Lastly, I am getting very poor FM reception, where is the aerial for FM in an E93 and where does it plug in to? Are there any options for improving the signal?

Thanks!

The unused connections are for the USB socket in the centre armrest (6FL) and (I think) for the Sirius module for our friends across the pond. Don't know whether it's also used for DAB in the UK?

Are you sure that the FM issue is down to the aerial? Many FM reception issues are down to poorly shielded cables being used to power a dashcam or phone or similar. Also, do you have a 12v to USB converter in either of your cigarette lighter sockets? They can be very "noisy" electrically, especially the cheaper ones.

e93 antenna is quite complicated because it switches from one to another when roof opened and closed

The e93 has two sets of FM aerials one for when the top is down and
another for when the top is up.
As pt explained.
