Yes...the "Euro" designation is due to them being aspherical (wide angle) mirrors which has the line running done the mirror glass that separates the "visually bent" section from the larger convex section.
But BEWARE...if your X5 has the auto-dimming side mirrors...these ARE NOT direct replacements...they are heated and aspherical...but they don't dim. If you don't know if you have the auto-dimming side mirrors...just look at the circumference of your mirror glass...if there's an obvious thick black band around the mirror glass...then it is the auto-dimming mirror. Also, if you remove the mirror glass from the housing...you will see not only the 2 wires for the heating elements...but another connector for the auto-dimming feature:
(thick black band around the circumference of the mirror indicates auto-dimming mirror)
{mirrors below are the Euro aspherical wide angle/auto-dimming/heated side mirrors front side}
{the mirrors below are the USA version auto-dimming/heated side mirrors - front side - plain glass on the left & convex mirror on the right}
{the mirror below are the USA version auto-dimming/heated mirrors - rear side - note the heating element wire connections & the auto-dimming connector (purple wire)}
The eBay link is selling mirror #1 in the diagram below. These mirrors aren't sold/offered to the USA market...due to BMW NA thinking we can't handle a convex mirror on the driver's side.
And sometimes I think they're right...because some Americans freak out when they drive any of my BMWs because I've always upgraded to the aspherical mirrors since they offer a much greater visual range of the traffic to your right & left.
