I bought the 500X Pop Star Multi Air in January, but the air conditioning is odd - anyone else had this? It has the dual zone climate control, but on the lowest setting 'Lo' it still gives out slightly warmed air, and certainly not the usually cooled air expected from air conditioning. I now find that it is best on any journey to set it at 16 degrees, with the air con off and allowing air in from the outside, to get any semblance of cool air from the vents. Certainly not what I expected. Can anyone tell me if theirs works better than this, so I have some levereage with my dealership, as they say it's all set correctly! Thanks.
