Some free Premium Connectivity and MCU upgrade questions

[Fragger]

Hello folks. Trying to fill in some gaps in my knowledge:

1. If Additional Vehicle Information screen shows "Tegra" that means MCU1, right?

2. What are the limitations of having FSD but on MCU1?

3. If MCU1 is upgraded, I assume the cost now is, $25XX+... What happens to the State of Premium Connectivity for free?

4. What are the downsides and upsides of MCU upgrade for infotainment components of the car? I hear you lose FM/AM radio?

5. If Free Unlimited Supercharging impacted at all by MCU upgrade?

Thank you for your help in advance!

3. If MCU1 is upgraded, I assume the cost now is, $25XX+... What happens to the State of Premium Connectivity for free?

- No impact to premium connectivity. It it was free before, will continue to be free after the MCU1 to MCU2 update.​

4. What are the downsides and upsides of MCU upgrade for infotainment components of the car? I hear you lose FM/AM radio?

- You do lose FM/AM radio. There is an option to get the FM tuner replaced for an additional $500, but no option to get back AM.​

- How much of an issue this is varies greatly by the individual. Many stream radio stations over TuneIn or other internet means.​

- You can find many threads that speak to the benefits. New main and dash screens, higher refresh rate on screens, improved​

internet browser functionality, theater mode works for many services, etc.​

5. If Free Unlimited Supercharging impacted at all by MCU upgrade?

- No impact to free unlimited supercharging. If you had it before, you'll have it afterwards.​

I personally chose to update in Dec 2021 and find that navigation significantly faster, which was worth it for me.

1. Right.
2. I don't think MCU1 FSD is eligible for FSD beta yet. The instrument cluster with FSD & MCU2 has an option for a more expansive view of the lines and vehicles around you. I like it. I also upgraded MCU1 to MCU2 and felt it was worth it. I didn't bother with the FM radio, although you can do that upgrade at a later time if you change your mind.

Keep in mind there is currently a bug affecting MCU2 audio performance.

Very helpful response! As I searched the topic, seems like MCU1 folks are eligible for FSD beta now?

As I look for the older Ss with Free Premium Connectivity and such that actually have FSD, I'm failing to understand why people would buy FSD without the MCU upgrade? Isn't it nearly useless without it?

Additionally, YouTube and such doesn't work without MCU either right?

Can you expand on that, my friend?

The current MCU2 software has periodic pauses in streaming audio. There is a thread in this forum about it.

That sucks man... Shame they haven't fixed it.

Anyone know of a visual test for knowing if the MCU got FM in it or it's only possible by tuning into the radio?

Look at the audio sources (audio settings -> sources). If FM is listed, it has FM radio.
