What E90/91/92 accessories would you recommend?

[G350]

I've had my 2011 E91 for a couple of months now and, need to get some accessories for it.

What accessories do you have and recommend?

What are genuine BMW ones and what are eBay jobs? I live about an hour from the dealer and am hoping not to be visiting him for a couple of years!

Top of my purchase wish-list was the iPod Y-cable but I just found out that one of the 2011 upgrades was that this was no longer required if you have the USB interface. All that was needed was the original Apple USB connector. Yay!

But I do need to get some rubber footmats (BMW ones are £60) and a boot floor protector, but which one? We've a solid boot tray in the Subaru which has been great but is awkward to store when not required and also when loading the car when the rear seats are folded down (as it has a ~20 cm lip).

Also particularly interested to hear if anyone has a "Seat back storage pocket" for the kids. They're pretty steep at "from £76" each but do look useful. Tons of cheapies on eBay but are they any good???

Those look horrible!

The only accessories I have is the genuine boot mat and the BMW roof bars which I use with 4 Atera Giro bike carriers.

I use the Y iPod cable in our Mini and it is brilliant but overpriced.
