Just picked up my car from SC. My MCU 1 went out in May. Wanted MCU 2 and was told it was not available. While waiting for MCU 1 replacement, someone called me on July 3 and offered MCU 2 as an option. He said it's easier to get MCU 2 than MCU 1. So, I opted for MCU 2. The quoted price was $2500 plus tax. When I picked up my car today I was given a $600 discount. I ended up paying $1900 plus tax. He mentioned that this will be the price going forward as far as he knows. My upgrade included a new screen and instrument cluster. My IC is not compatible with MCU 2. The price they quoted me for MCU 1 was close to $1800 (including tax). Essentially for a couple of hundred dollars more I got MCU 2. Well worth the extra money in my opinion. He said there is still a two to three weeks wait for MCU 2. My brother in-law has MCU 1 in his X under warranty and is scheduled for the end of August for MCU 2 upgrade. He was also quoted the $1900 plus tax. Again, my MCU 1 was out while my brother in-law's MCU 1 is working fine. He just wants the upgrade. As far as the upgrade, nothing transferred. I think in my case because my MCU was out. I made sure the app works and both keys before leaving the SC. I want to thank @Akikiki a forum member with all the questions I had with this upgrade.
