E70 X5 Isofix

[Steve996]

Boring question I know! Anyone else using their X5 with a Stokke Isofix base/new born car seat? I am a bit concerned that the angle of the X5 seat results in the rear facing car-seat being canted forward more than I'd like. I've spoken to Stokke and they can do nothing, albeit they list the X5 as compatible, I've spoken to BMW and nothing can be done to alter the seat angle??? Anyone else got any general views on Isofix with an E70 X5 and in particular with the Stokke system specifically.

Apologies again for a boring tedious non-PH question!
