I have noticved that here in the UK we have an alternative option - not sure if you can get it in your region.

The BMW UK website lists this one:

BMW UK: Owner area - Genuine BMW Accessories

Which looks identical to the Nextbase Click & Go 7 Duo, save for the stickers. The advantage of this one is the price, which works out at around $600.

Alternatively, I have seen the nextbase version on Amazon for a lot less, although you would need to but the brackets separately.

I have an X5 on order and the only thing stopping me from ordering one is that I would like to keep the screens in the centre console storage when not in use and am not sure whether the 7 inch or better still the the 9 inch screens would fit.
