So what is the deal with this adapter...? I remember reading threads where people were having problems like it would work and not work, and when it worked it would disable the HVAC controls/tone controls.

Has this been fixed?

If so, I have a '04 TSX (no xm, no navi), which model should I get (I don't need Ipod controls and such)? I remember seeing a couple of versions out there... DMX V2 and some other one... and where can I get the best price?

or would you guys recommend other options like PIE or SNHOND3?
