hey guys- i have been looking at a couple of 550's. what is the exact deal with the hvac control panel bubbling ? is it a overlay sticker that de-laminates ? what are the options and $ for a factory replacement ? i recall seeing a user her on fchat that offered a refurb and i know a sponsor offers a carbon version upgrade. how difficult would it be for an end user to swap out or is it a dealer job ? thanx
