Yes, that's roughly what I was charged about a month ago - I think part of it is also the FM tuner portion ($690) as you lose AM/FM with the MCU2 upgrade ($2K) but with an added module you at least get back FM. I was on the fence about it, but since then I'm liking the change. Voice commands actually work and are expansive! The Dashcam/Sentry and the ability to view it, there's other things that came with MCU2 that didn't come with MCU1 and everything seems to be much more snappy.
Don't forget labour is on top of this, so you're approaching $3K by the time it's all done (if they don't find something else that needs fixing).
