Oct 2016, MS, MCU1/AP2.0. I think Tesla is making it very clear that MCU 1 is being left behind in any future updates in function, as evident by the new back up camera/side camera display. It's an old beaten horse that needs to be put out to pasture.
I decided to bite the bullet and scheduled the upgrade to MCU2. I just received notice of the following part number ordered, which is different than others I have seen posted. I have not received my service estimate yet. Has anyone seen this part listed? Usually, it is the same part number with "-A" that I have seen. What could this be "WITHOUT DISPLAY?" I had already scheduled the FSD computer upgrade but pushed out the appointment to allow the ordering of the MCU2 upgrade as well.
MCU INTEL HW3 UPGRADE-For TegraAP2.0 - WITHOUT DISPLAY - NORTH AMERICA
Part #: 9874562-00-B
Glad you are receiving the parts ordering email. It seems to me, based on my experience, that this is a necessary step to schedule your service. It is possible to receive a service estimate without a parts order, but it seems like service centers currently have very low supply of infotainment upgrade components, so they have to order the parts.
I went through several iterations and 5 service estimates before my car went in for the upgrade yesterday. I did receive a parts ordered email, a parts shipped email, and finally (but after my car was in for the upgrade) a parts delivered email.
Originally, service centers were incorrectly putting the upgrade kit for an AP2.5 car on my service estimate:
MCU INTEL HW3 UPGRADE-For TegraAP2.5- NA (9874561-00-A)
Then, after some back and forth, a different service center put the upgrade kit for a AP2.0 car on my service estimate:
MCU INTEL HW3 UPGRADE-For TegraAP2.0- NA (9874562-00-A)
And, most recently, after switching to the Costa Mesa service center, the following parts were put on my service estimate (and these are the parts that were ordered):
MCU ASSY. W/DISPLAY, NO SIM, FUSED, NA(1451809-S0-B)
INSTRUMENT CLUSTER(1447934-00-E)
I do suspect that these parts are selected based on what is on hand at the service center. Your service center may have instrument clusters for MCU2 and even the display for MCU2. My service center may have needed both the MCU processor, display, AND the instrument cluster.
I hope your parts are shipped and delivered promptly.
