I do use Slacker Radio, (LiveOne) or Streaming...

    Anyone else with sluggish MCU2?

    It seems the UI frequently hangs these days. Seeing as V11 has been out for a while I’m assuming it’s not just a case of an unoptimized first release. Anyone with MCU2 starting to see performance issues ?

    Periodic Loss of Sirius/XM After MCU2 Upgrade and 12V Replacement

    About six weeks ago I sprung for the MCU2 upgrade with the $500 FM/XM tuner option in my 2013 MS. Other than some initial challenges getting the new XM radio ID connected to my account, the system worked perfectly. Last week, the 12V battery gave notice that it was dying so I scheduled mobile...

    HPWC no longer charging after Infotainment Upgrade

    I've got an V1 HPWC that charges at 80 amps on my dual charger P85D. It worked in a bulletproof fashion for many years. I brought the car in to replace a leaky LCD screen and they convinced me that the Infotainment Upgrade made more sense, so I did it. However, ever since I brought it home...

    Does MCU2 fix bluetooth audio / video delay?

    One of the things I'd like to do is watch Netflix on a tablet or phone using the car's audio. Unfortunately, in my 2016 model S, there is a full second of bluetooth audio delay between the video on the device and the sound coming out of the speakers. My previous car, a 2015 Hyundai Sonata, had...

    HELP! MCU1 died. Anyone know how I push to get MCU2?

    I have a Feb 2017 Model S 90D. My MCU1 completely died. I dropped it off at service center and asked if I can pay the difference in price to upgrade given the car is under warranty. Might as well, right? But, he said only Tesla owner's who have been given the offer can upgrade. Is that true...

    Tesla Charging $2200 for MCU1 replacement

    My 2013 Model S VIN 13xxx MCU went dead. I was hoping to purchase MCU2, but Tesla Service Center Santa Clara is saying my VIN is too old to take MCU2 replacement, so they're charging $2200 for MCU1. Anyone know about the VIN cut off for MCU2? According to the article, they said: "All remaining...

    Wiki FAQ: MCU2 Upgrades

    Ok, so I think it's in the best interest of the community to have a sticky on what is and is NOT included with the Infotainment (aka MCU) upgrade, and to further clarify that it is separate from FSD (also referenced by APE/AP/HW3) Descriptions of MCUs and HWs below questions (via TeslaTap) Q...

    Does FSD Computer Upgrade also Upgrade the MCU?

    I'm on an MCU1 with Autopilot 2.5. Does anyone know if the Full Self Driving computer upgrade is the same as upgrading the MCU? Right now on V10 Cuphead, Tesla Theater & Caraoke aren't enabled. After a fsd computer upgrade should I expect that anything changes?

    Tesla infotainment system upgradeable from MCU1 to MCU2

    So my 2017 S is showing the dreaded yellow frame on the center screen. I obviously need to get the screen replaced and in reading through the threads on here it appears Tesla is now just swapping screens when possible and not touching the MCU. Since these two are so closely married and I have...

    Reboot loop

    I've had my X100D for 5 days. Since then, I have rebooted the car 4 times. Three of those 4, the car went into a loop where the IC screen would flash the Tesla logo and then come up for maybe 5 seconds and then reboot again. The MCU remained black the whole time. I made a small video today...

    Immersive Sound on New MCU?

    Sound on my March 2018 Build Model S 100D seems significantly better than it was on my 2017 March Build Model S 90D. It’s actually amazing! Is it possible that this is a carryover from the Model 3 which shares a similar if not the same MCU? Is the Immersive New sound option a firmware thing...
