So.. if you get MCU2 upgrade done, they also install AP 3.0 hardware so when you pay for/enable FSD at later date there is no need to go back for anymore "hardware work"?

Yeah I got it on our Model X. Even without FSD, I could now turn on FSD visualization so I see all the traffic lights and trashcans on the side of the road LOL. The trashcans graphic is pretty impressive on trash day!

The FSD should be a reduced price for any car with EAP, first owner or not. EAP already includes much of what is in the current version of FSD.

I agree it might be better to get FSD now to avoid future price increases.

Great call out re FM radio - we love local radio and will probably wait until we can get FM down at same time with MCU. I saw some in Europe were getting FM radio with MCU2 already?

BTW - I spoke to two Tesla SC and sales ppl today - everyone 99% sure the $6500 upgrade for FSD will carry over to me from previous. They made a point of emphasizing that upgrades travel with car. But of course no written guarentees:)

the senior tech said he would go with FSD upgrade in app first and then come in to do MCU2/AP3 in one shot.

You should really drive the car with EAP it does a lot already and FSD is just not there I wouldn’t necessarily prepay it ..u will get a lot of functionality from MCU2 immediately on install ...the MCU 1 is just useless with navigation etc in its current form running latest firmware ...EAP (the old version ) is really good IMO

Yah you are right - I will drive it as is and get used to it before making decisions.

Maybe a Black Friday or Boxing Day FSD upgrade sale if we are lucky:)?

the price fluctuates so much on FSD it now shows $7000 USD in my app..my comment was more along the lines of i personally would separate decision of mCU 2 upgrade and FSD as the MCU2 adds a lot of value now ..and the old EAP offers a lot of functionality already ..ie summon ..auto park ...auto lane change ...nav on autopilot ..etc ..than the new AP feature set u get now with a new purchased car :);)

Scattered in the trades/e-zines and here on TMC, there's lots of recent info about FSD Beta. The "team" would not be investing all this effort in a complete rewrite of FSD for FSD Beta if they did not intend to permanent develop it and deploy it versus the former product we thought of as FSD. Maybe its a good idea to look around for some exclusive FSD Beta videos and threads here. I've been in a FSD Beta car. Its very impressive. Enough about that now.

As you watch the FSD Beta videos watch the transitions. Some drivers even talk about it. The cars start off with FSD Beta in town/city/street driving. That's where we see FSD Beta's visuals that are so impressive as it manages to move the car and avoid "stuff". But when the drivers get on divided highways and interstates, you see the car's system transition the car to use EAP/AP until it is ready to exit. Then it comes back to FSD Beta. Simply watching the various FSD Beta videos as it starts FSD Beta, transitions to AP and back explained more about AP/EAP/NAP and FSD than any reading, any explanation that I had previously seen. And FSD Beta is coming to more cars this week. Very cool stuff - finally.

If you think, if you see posts that MCU1 is struggling to run the car and work with AP3 hardware now, when this new version of FSD Beta installs on MCU1 cars, - I believe the car is going to be overwhelmed with the high intensity images and processes in FSD Beta.

HI - taking possession of a used 2017 MX 100D later this week. Owner bought EAP but never paid for FSD but has FSD upgrade available in App for $6500 CAD. AP is 2.0 and MCU is 1.0.

My initial thinking was to immediately go in and get MCU 2.0 upgrade (~3500 CAD) as it is a bit sluggish and postpone FSD $6500 for some time until we can do more with it here in Canada. During inspection, the Tesla guy said to get FSD done right away before price goes up and then go in and get MCU 2.0 + AP 3.0 done at once. I'm torn now as that is 10k CAD of upgrades - albeit important upgrades.

Any chance the quote will be less for doing both or is it truly 10k? am i better to do together or does it matter?

Hey Tommy. I am a newbie and know nothing about Tesla's but am thinking of purchasing one in the future so I am on here to study and learn. What is EAP, FSD, MCU please? Thanks.

Unfortunately EAP is used in 2 capacities. In this thread it is referring to Enhanced Autopilot.

MCU is Media Control Unit, and is not often talked about with model 3/Y because they all have the latest version. For model S/X, there was an earlier MCU hardware up to March 2018.

Thinking of other model X specific acronyms... FWD is falcon wing door.

I recently did MCU 2 upgrade. I can certainly say it was well worth the money for everything I got. MCU 2 upgrade included AP3 aka HW 3, updated instrument cluster screen as well. With all known issues with MCU 1, it will have issues down the road eventually. Once you get mcu2 you will realize how slow is mcu1.
EAP is very capable, I use it almost all the time in the highway. Only thing FSD will give is city driving and stop on light and signs. Personally I don’t see the value for the money for those 2 features. If you only have AP, I can see the value, with EAP, it is a minor upgrade.

So confirming then that MCU2 upgrade includes all the AP3 pieces as well even if you have not bought FSD prior to upgrade? I.e. when you decide to do FSD upgrade down road, you'll have all the HW and no need to revisit SC
