It works ok for me but it's far from my most common setting.
I set the vents to recirc when I'm on that setting and it does ok.
My feet get WAY too hot usually though, so I tend to just leave on top-only with just enough air to keep my hands warm on cooler days.
If my feet get cold, I just switch back to upper/lower.

 

Probably the radio is overheating and just needs to be reset...

 

I use it ALLLL the time,,, Here's what it does,,, If you use the, upper/lower setting,, the wind from driving with the top down, will "take" the heat coming from the upper vents because they are high in the dash,,, if you use the top down setting,, it blows the heat on your feet,, AND from the small vents right above the center console,, RIGHT into your lap basicly,,, I think it works well,,,

 

Yeah I knew it was overheating the radio, but it shouldnt be able to do that! I guess ill just have to live with it..just wondering if anyone else had this problem..

 

i do the same too, but it works great for me when the top is down

 

my s used to be a sweat box; it worked great.

 

yeah I love the convertible setting. I never use any of the other settings, bc I have contacts. Having hot air blow in my face only causes my contacts to dry out and it causes them to become uncomfortable. Now the 105 degree summers are a different story.
