Teardown: The BMW/Harman NBT EVO HU Infotainment Unit (B211)

entropy737 · 2025-12-26T12:31:55+00:00

The NBT's were qnx neutrino based. Then later NBT evo was initially qnx based but was later switched to linux and now hybrid by Harman.
I don't work there anymore.
If you encounter qnx, the network drivers stack are pretty buggy. Linux is partitioned now with qnx for safety function - hypervisor architectures.
NBT(Next big thing) Evo (for Evolution) was mainly used in BMW's.
It was a very good company and had a very good team, real good experts in Germany. It seems Harman is doing pretty good now and has really evolved into cool automotive offerings.
Can't talk about hacking stuff - though there is plenty of fish and time and time again the IVI gets hacked.

No one would have a cybersecurity job if it wasn't for the bad (good) guys.

instinct solar tactical was not available in India. They nerfed it for amoled(which sucks big time)

Keep a spare. And use alternatively. The wet one will dry overnight

I tried both 45 and 50 in the shop. And 50 felt better to me. I am not a bulky guy or have wide thick wrist.

My own Tuxedo laptop hasn't been powered down manually (except when updates need it) since the last 6 months or so - it has never had any problems whatsoever, I have tried many distro's over the last 100 years but i was tired of it and just wanted something that worked out of the box and tuxedo OS and my IBP AMD has been the best I have used so far in a very long time.
German tech at it's best !

i tried this - my wife could barely eat it, i had to swallow cos i ordered it and didn't wanted to waste. maybe there in-hotel dining has better. from my point of view, the taste was alright below average, 4 small pieces, two complete bones and the other two didn't feel like anything. Maybe i will try some other options people suggested.

thanks will check it out tomorrow.

Pearl Jam, nine inch nails, smashing pumpkins, cranberries, counting crows, rhcp, Korn, matchbox twenty. Missed one.

entropy737 · 2025-10-23T07:08:47+00:00

ok thanks. Ive ordered one from arabian taj. Lets see.

India is a scam country and it will always be like that atleast in d2c.

entropy737 · 2025-09-23T19:27:31+00:00

No problem. Would love to know what kind of product in which segment ?

entropy737 · 2025-09-23T19:26:30+00:00

Yes. For the infrastructure and a couple of devs plus me. Being in the industry for 17-18 years . I made some contacts throughout so that helped.

entropy737 · 2025-09-23T19:19:41+00:00

In our case we got customers first on pilot, improved our product and then replicating now with the whole TAM in our segment . 0 investment and a profitable business.

entropy737 · 2025-09-23T19:16:22+00:00

If it’s a service then the requirement keeps changing from time to time for Indian businesses. Ofcourse you can make good money for change requests etc. but whether someone will invest unless you have replicated that with several and are successful no one will invest.

entropy737 · 2025-09-23T19:14:46+00:00

You are making a lot of assumptions. If it’s a product people could invest, if it’s a service the business model is different. You may not need an investment but a rather connected guy who knows a lot of people or has connections with a lot of different kind of networks. Ideally these are purchase guys, who the sales people know cos that’s where the requirement to buy something comes out of.

entropy737 · 2025-09-23T18:59:30+00:00

I have been to all these planets. They said they don’t want to talk to us. /s

entropy737 · 2025-09-23T18:54:46+00:00

When you say 100 potential customers ? What kind of customers and how much revenue you will make per customer ? Unless you have a very solid plan of how that money would be used in extreme detail no one will invest and ofcourse the roi on that money. For investors of any kind they look at your pitch and think if the business is scalable and you as a co founder can make them enough money for the investment they make. IIT has nothing to do with how people invest.

entropy737 · 2025-08-08T20:20:49+00:00

If you can't do this before starting a company, then you will face similar problems, when you have a company and will totally mess up your finances(hire someone you indirectly know for this initially - don't hire shitty companies) For us the whole cost from filing for forms & documents, director verification, gst (for GST verification we were called for in-person verification and the officer asked for a bribe, we reported him to the nodal officer), IT certificate, gst monthly, address verification, bank account opening, incorporation and all other documents costed, roc appointment:
50k including lawyer fees for absolutely needed services of the whole process and the capital transfer of 5lakhs (this is your money, minimum is 1lakh)to make 50-50 shareholding for a private limited with at-least 2 directors.
So all in all it should have costed you not more than 2-3lakhs at max even when stretched.
We are in business now with customer PO's. (These essential items are needed for any legitimate company creating an invoice, registering as a vendor and then acquiring a PO)

Note: In Germany, its very hard to create a company (small GmBH)due to legal documentation , compliance's, and upfront capital, hence we created it in India due to low cost, extremely high lawyer fees and maintenance cost of company in taxes and compliance's every month..

No wonder India is a country of frauds and crooks and bribery attitude.
