I would say the odds are good you'll have to get that trim off.
Honestly I haven’t spent any real time in a 08.
(Well at least not in a 08 that had an interior

)
So I haven’t a clue how they work.
Did you find my DIY for the classics? It should at least give you a starting point. I haven’t look to see if there are any 08 DIYs that involve removing the center trim; you might want to look for that. Also the “other site” tends to have a more complete tech section.
