I'll look into it and let you know what I find out... Either way, definitely hoping this will make my coupe sound like my old roadster.

Thanks. I guess my question really relates to whether the updated nav firmware (v.32, etc.) has any effect on the amp coding as I know the systems are interconnected? Just don't want to recode the amp only to undo it with a navi update or update the navi only to find that the amp fix doesn't work, etc. Any insight...?
