As a Tesla Model S owner, I was starting to notice that my infotainment center was becoming slower and less responsive over time. This was particularly frustrating when trying to use the built-in navigation or stream music while driving. After doing some research, I discovered that there was an upgrade available that could significantly improve the performance of my car’s infotainment system: the MCU 2 upgrade.
I figured I’d detail my experience for anyone thinking of doing this upgrade.
The MCU (Media Control Unit) is essentially the brain of the Tesla infotainment system. The original MCU in my Model S was MCU 1, which was released in 2012. The newer MCU 2 was released in 2018 and featured a faster processor and more memory, which resulted in a much snappier and more responsive user experience.
To start the upgrade process, I made an appointment with my local Tesla service center. The upgrade itself takes “a few hours”, and the service center did not provide me with a loaner car to use while the upgrade was being performed. Tesla dropped the price from ~$2000 to $1500 for the upgrade in January 2021 but then upped the price $250 to $1750 in late 2022.
I bought my car in mid-January of 2023 and set up an appointment on January 20th, 2023. Tesla initially had it listed as a mobile technician appointment for the next day but then changed the date to a week later at the Carlsbad service center.
They then delayed my appointment by a week, then another, then two weeks until my new appointment was February 17th. At this point, I was given a quote that came out to $1750 plus tax, and $0 for labor.
The installation itself took over a day, with little progress being made on the first day. About 4 minutes before closing on the second day the car was ready but I was not able to pick it up until the following day.
When I picked up my car, I was immediately impressed with the difference in performance. The navigation system was much faster and smoother to use, and streaming music was no longer a frustrating experience. In addition to the improved performance, the MCU 2 also offers some additional features, such as the ability to view streaming video from YouTube, Twitch, or Netflix.
Something that was not really brought up but I immediately noticed is the change in visual clarity on the new display. It had blacker blacks and deeper colors that made it much more enjoyable to use.
Since the installation, the only issue I’ve had is that my homelink no longer works but I am going to attempt to get this remedied soon. Other than that the car seems to think it is at the Tesla headquarters at all times and I’m not sure why.
Overall, I’m extremely happy with the MCU 2 upgrade. It’s a significant investment, but it has made a noticeable difference in the usability and overall enjoyment of my Tesla. If you’re experiencing similar frustrations with your Tesla’s infotainment system, I recommend considering the MCU 2 upgrade.
I did the muc2 upgrade too. I have some bugs which only coud besolved with a reset. I didn’t have these problems with mcu1, like trunk open latch button doesn’t work. Controls from tesla app sometimes does not work. frunk only opens by keyfob. user presets does not apply by changing user.
Also home link does not work any more (EU homelink 2), have you fixed it? and how?
With mcu1 my car could sleep for hours. now with mcu is sleeps only fo mostly exact 43 minutes before it wakes up for a coupe of minutes to 1 hour max.
The UI of mcu is much fast and smooth. I had to replace the muc due to screen bubbles. But if i knew these problems i probably would have kept mcu1.
My homelink began working a few days after I wrote the post, haven’t had issues since. The sleep thing does sound like how mine behaves but I haven’t had an issue with that behavior. For the other things it might be worth asking them to look at it again, you should have at least a year of warranty.
Glad to know this information. Confirmed is what a Tesla technician told me of experiences where I live – Tacoma Washington. Shop is in Fife. I have a sunroof, want to keep it, and executive seats. The extra seats not really needed. With only 62K the computer (car basically a computer on wheels) should last a long time. The circuit breaker fuse for my battery pack was just replaced under the about to expire warranty so I am happy enough. Improvements with the monitor would be good. I hope the radio reception improves too? Thanks.

If you mean radio as in am/fm, they actually don’t have that in mcu 2 except as an optional – I think $500 – upgrade.
Cell radio reception is way better since they replace your 3g only modem with a 4g capable one thats much faster.
I also have a 2015 MS85D and thinking about this MCU2 upgrade. What software version are you on? My with MCU1 is only on 2022.9.10.12. Were there any improvements with the AP1 and/or supercharging improvements when you did this MCU2 upgrade? Thank you.
I am on the latest ( 2023.20.7 ). No improvements with autopilot but the charging starts way faster, car starts way faster, everything feels much smoother its like a completely different car.
