[MTCD Android Head Units General] typos1:
Hotaudio is a manufacturer, they have a thread on XDA, like it or not, this is a fact, its "official".

We are talking about Chinese manufacturers that only deal with retailers, not members of the public, this is why why you wont find any manufacturer's sites with MCU updates, or indeed Android updates. The factory settings passwords are freely given out by most sellers. The lack of OTA updates is not evidence thats it isnt a good idea to update your MCU if a new one is available. Its evidence that the manufacturers and sellers dont want to spend the money writing the software and running the servers to do it.

As I ve said, most sellers know very little about what they sell, they are only good as sources of updates and warranty claims, in fact often theyre not even good for warranty claims. People "updating for no reason" is the cause of not a single problem - problems after updating MCUs are incredibly rare. Its also not true to says that "sellers recommend not updating the MCU", some do, some dont. These units are different from other products, for reasons I ve already explained - most sellers know very little about what they are selling and are useless, I ve said it and there are 1000s of posts in these forums saying it, so you can insist thats not the case as many times as you like, but most on here will disagree with you. "Dont fix what isnt broken" is not a phrase that applies here, or with computers generally - software is constantly evolving, constantly improving. I m not sure how you tested whether an MCU update made any difference to your unit, did you assess all the billions of computations done by Android and the MCU and compare them before and after the updates ? Just cos you happened not to notice minor improvements does not mean that there werent any.

These units are computers and the way it works with computers is that there are often updates to install and almost always its best to install those updates, for all sorts of reasons, including security ones, thats how computers work. I take it you dont install a single update on your Android or Apple smartphone then ? I take it you dont update your Android or iphone apps ? You dont install a single update on your Windows or Apple or Linux laptop or desktop ? You may choose not to, but its not good practise, its not what most people choose to do and its not the way computers work.

I never said the manufacturer wants us to keep our units up to date, I said its best practise to update the MCU if one is available. The manufacturers would rather we updated our units by buying nice new ones cos theyd make more money. Its not about what the manufacturers or sellers want, its about whats best for using these units and that is almost always to update to the latest MCU as soon as one is available. In 5 years and 100s of updates I ve only ever had one very minor problem after updating an MCU, I simply downgraded to the previous version and waited for the next update, which worked fine, every time an MCU update comes out I update my unit. There are literally 100s of 1000s of posts in the MTCB and MTCD forums backing this up and very few where people have had problems (and when they do, theyre often theyre caused by the user). I ve got nearly 5 years experience of these head units, I ve lost count of how many I ve had, 99% of my thanks and 95% of the posts I ve made are from and in the MTCB and MTCD forums, I do know what I m talking about.

Every time you drive your car there are risks involved - the probability of an accident is far, far greater than the risk of an MCU update causing a major problem on your headunit, yet you still drive your car. The risks of updating an MCU are very minor, very rare and can be fixed anyway even if the unit bricks, youre blowing things way out of proportion, being way, way too conservative, its like youre almost afraid to even touch your unit lest it break. I ve never come across some one so afraid to update as you here, thats your prerogative, but youre in a minority (of about 1), thats not the way most users here think, which is why we have threads with "latest updates" in the title. There are 1000s and 1000s of posts in the MTCB and MTCD forums disproving the reasons you give for your opinions, dont update if you dont want to, but most people do with no problems. Why are you even posting in a thread about updates if youre so dead against them anyway ?!

No MTCB/C/D/E manufacturer has ever posted anywhere telling people not to update their MCU.

With the exception of Hotaudio, manufacturers dont post links to software for the public.

From your post its clear that there are lots of things about these headunits that youre not aware of, you should spend some time reading threads in the forum and the wiki to gain a better understanding of them.
